Abstract: The TOTEM experiment, small in size compared to the others at the LHC, is dedicated to the measurement of the total proton–proton cross-sections with a luminosity-independent method and to the study of elastic and diffractive scattering at the LHC. To achieve optimum forward coverage for charged particles emitted by the pp collisions in the IP5 interaction point, two tracking telescopes, T1 and T2, will be installed on each side in the pseudo-rapidity region between 3.1 and 6.5, and Roman Pot stations will be placed at distances of 147 and 220 m from IP5. The telescope closest to the interaction point (T1, centred at z=9 m) consists of Cathode Strip Chambers (CSC), while the second one (T2, centred at 13.5 m), makes use of Gas Electron Multipliers (GEM). The proton detectors in the Roman Pots are silicon devices designed by TOTEM with the specific objective of reducing down to a few tens of microns the insensitive area at the edge. High efficiency as close as possible to the physical detector boundary is an essential feature. It maximizes the experimental acceptance for protons scattered elastically or interactively at polar angles down to a few micro-radians at IP5. To measure protons at the lowest possible emission angles, special beam optics have been conceived to optimize proton detection in terms of acceptance and resolution. The read-out of all TOTEM subsystems is based on the custom-developed digital VFAT chip with trigger capability.

Abstract: The energy of atmospheric neutrinos detected by MACRO was estimated using multiple coulomb scattering of upward throughgoing muons. This analysis allows a test of atmospheric neutrino oscillations, relying on the distortion of the muon energy distribution. These results have been combined with those coming from the upward throughgoing muon angular distribution only. Both analyses are independent of the neutrino flux normalization and provide strong evidence, above the 4 sigma level, in favour of neutrino oscillations., 10 pages, 7 figures, submitted to Physics Letters B

Abstract: The upward-going muon flux (Eμ > 1 GeV) has been measured with the underground detector MACRO at LNGS. The total number of measured events is compatible at the 8% c.l. with the expected one. Moreover, the zenith angular distribution of the measured flux does not match the expectation showing a deficit in the vertical direction where the apparatus performance is best known. Assuming an oscillation hypothesis with parameters in the range recently suggested to solve the atmospheric neutrino problem, the agreement increases, but not significantly. The results of an indirect dark matter search for a signal of WIMPs from the core of the Sun and of the Earth are given. Neutrino astronomy with MACRO is giving interesting results regarding possible high energy neutrino emission from pointlike sources and coincidences of neutrino events with γ-ray bursts.

Abstract: The TOTEM experiment is dedicated to the measurement of the total proton–proton cross-section with the luminosity-independent method and the study of elastic and diffractive scattering processes. Two tracking telescopes, T1 and T2, integrated in the CMS detector, cover the pseudo-rapidity region between 3.1 and 6.5 on both sides of the interaction point IP5. The Roman Pot (RP) stations are located at distances of ±147 m and ±220 m with respect to the interaction point to measure the very forward scattered protons at very small angles. During the LHC technical stop in winter 2010/2011, the TOTEM experiment was completed with the installation of the T1 telescope and the RP stations at ±147 m. In 2011, the LHC machine provided special optics with the large s⁎=90 m, allowing TOTEM to measure the elastic scattering differential cross-section, down to the four-momentum transfer squared |t|=2×10−2 GeV2. Using the optical theorem and extrapolation of the differential cross-section to t=0 (optical point), the total p–p cross-section at the LHC energy of s = 7 T e V could be computed for the first time. Furthermore we measured with standard LHC beam optics and the energy of s = 7 T e V the forward charged particle pseudorapidity density dn/dη in the range of 5.3

Abstract: MACRO is a large area multiple component detector located deep underground in Hall B of the Laboratori Nazionali del Gran Sasso in Italy. Its active components consist of tanks of liquid scintillator and planes of limited streamer tubes. In addition, there are two planar areas covered with passive track-etch plastics. The full detector measures 72 m × 12 m × 9.6 m providing a large sensitive area for the detection of penetrating particles. Multiple electronics systems provide triggering on particles over a wide range of velocities, in particular, for slowly moving massive particles such as grand unified magnetic monopoles. MACRO is sensitive to relativistic particles as well as ones whose velocities are as low as 10 −4 c. Various portions of the MACRO detector have been operational since 1989. Various data sets have been analyzed and although no monopoles have been found, stringent flux limits have been set using a variety of techniques. This paper summarizes the capabilities of MACRO for monopole detection and presents some experimental results which have been obtained to date.

Abstract: A search for lightly ionizing particles has been performed with the MACRO detector. This search was sensitive to particles with charges between $\fractional{5}$$e$ and close to the charge of an electron, with $\beta$ between approximately 0.25 and 1.0. Unlike previous searches both single track events and tracks buried within high multiplicity muon showers were examined. In a period of approximately one year no candidates were observed. Assuming an isotropic flux, for the single track sample this corresponds to a 90% C.L. upper flux limit $\Phi \leq 9.2 \times 10^{-15} cm^{-2} sec^{-1} sr^{-1}$ ., Comment: 15 pages, 7 figures, to be submitted to Phys.

Abstract: We present the measurement of two event samples induced by atmospheric $\nu_\mu$ of average energy $ \bar {E}_\nu \sim 4 GeV$. In the first sample, the neutrino interacts inside the MACRO detector producing an upward-going muon leaving the apparatus. The ratio of the number of observed to expected events is $ 0.57 \pm0.05_{stat} \pm0.06_{syst} \pm0.14_{theor}$ with an angular distribution similar to that expected from the Bartol atmospheric neutrino flux. The second is a mixed sample of internally produced downward-going muons and externally produced upward-going muons stopping inside the detector. These two subsamples are selected by topological criteria; the lack of timing information makes it impossible to distinguish stopping from downgoing muons. The ratio of the number of observed to expected events is $0.71 \pm 0.05_{stat} \pm0.07_{syst} \pm0.18_{theor}$ . Using the ratio of the two subsamples (for which most theoretical uncertainties cancel) we can test the pathlength dependence of the oscillation hypothesis. The probability of agreement with the no-oscillation hypothesis is 5% . The deviations of our observations from the expectations has a preferred interpretation in terms of $\nu_\mu$ oscillations with maximal mixing and $\Delta m^2 \sim 10^{-3} \div 10^{-2} eV^2$. These parameters are in agreement with our results from upward throughgoing muons, induced by $\nu_\mu$ of much higher energies., Comment: 7 pages, 6 figures. Submitted to Phys. Lett. B

Abstract: We perform an indirect search for Weakly Interacting Massive Particles (WIMPs) using the MACRO detector to look for neutrino-induced upward-going muons resulting from the annihilation of WIMPs trapped in the Sun and Earth. The search is conducted in various angular cones centered on the Sun and Earth to accommodate a range of WIMP masses. No significant excess over the background from atmospheric neutrinos is seen and limits are placed on the upward-going muon fluxes from Sun and Earth. These limits are used to constrain neutralino particle parameters from supersymmetric theory, including those suggested by recent results from DAMA/NaI., Comment: 14 pages, 7 figures, submitted to Phys.

Abstract: We present a measurement of the underground decoherence function using multi-muon events observed in the MACRO detector at Gran Sasso at an average depth of 3800 hg/cm**2. Muon pair separations up to 70 m have been measured, corresponding to parent mesons with P_t < 1-2GeV/c. The accuracy of the measurement is such that the possible contribution of rare processes, such as mu + N ----> mu + N + mu- + mu+, can be experimentally studied. The measured decoherence function is compared with the predictions of the hadronic interaction model of the HEMAS Monte Carlo code. Good agreement is obtained. We interpret this agreement to indicate that no anomalous P_t components in soft hadron-Nucleus and Nucleus-Nucleus collisions are required by the MACRO experimental data., 38 pages, Latex, 10 figures, Corrected typos

12. A transition radiation detector for particle astrophysics experiments using low power consumption electronics

Abstract: We have designed a transition radiation detector (TRD) of about 75 × 80 cm 2 active surface to discriminate positrons from protons in an experiment to be performed on balloon flights to search for primordial antimatter. The TRD is made of ten modules consisting of a carbon fiber radiator followed by a multiwire proportional chamber (MWPC). In order to achieve a proton-electron rejection factor of the order of 10 −3 with a strict limitation on power consumption to 35 mW per MWPC channel, as required by experimental constraints, we have developed and tested a prototype based on low power consumption “cluster counting” electronics. Comparisons of the performances of this prototype are made with those of a previous similar detector equipped with standard fast electronics and an analogous TRD from other authors.

Abstract: We have carefully implemented a transition radiation detector prototype in order to design a similar device having 75 × 150 cm 2 active surface that will discriminate positrons from protons. This detector will be part of the spectrometer of the experiment WIZARD, planned to fly at 180 miles altitude on the NASA Space Station “FREEDOM” to search for primordial antimatter. Since the positron to proton ratio is expected to be of the order of 10 −4 , we have pushed the proton rejection factor of the spectrometer beyond this value using a compact transition radiation detector equipped with properly designed “cluster counting” electronics.

Abstract: Using data collected by the MACRO experiment during the years 1989-1996, we show evidence for the shadow of the moon in the underground cosmic ray flux with a significance of 3.6 sigma. This detection of the shadowing effect is the first by an underground detector. A maximum-likelihood analysis is used to determine that the angular resolution of the apparatus is 0.9+/-0.3 degrees. These results demonstrate MACRO's capabilities as a muon telescope by confirming its absolute pointing ability and quantifying its angular resolution., Comment: 14 pages, 8 figures Submitted to Phys.

Abstract: Multimuon data from the MACRO experiment at Gran Sasso have been analyzed using a new method, which allows one to estimate the primary cosmic ray fluxes. The estimated all-particle spectrum is higher and flatter than the one obtained from direct measurements but is consistent with EAS array measurements. The spectral indexes of the fitted energy spectrum are 2.56[Formula presented]0.05 for [Formula presented]500 TeV and 2.9[Formula presented]0.3 for [Formula presented]5000 TeV with a gradual change at intermediate energies. The average mass number shows little dependence on the primary energy below 1000 TeV, with a value of 10.1[Formula presented]2.5 at 100 TeV. At higher energies the best fit average mass shows a mild increase with energy, even though no definite conclusion can be reached taking into account errors. The fitted spectra cover a range from [Formula presented] 50 TeV up to several thousand TeV. © 1997 The American Physical Society.

Abstract: Upward-going muon events collected with the lower half of the MACRO detector have been analyzed in order to search for Weakly Interacting Massive Particles possibly trapped in the core of the Sun and of the Earth. No statistically significant signal could be discriminated over the possible fluctuations of the atmospheric neutrino background. Assuming a particular neutralino model, the explorable neutralino mass region has been considered.

Abstract: We report on the first measurement of the flux of upgoing muons resulting from interactions of atmospheric neutrinos in the rock below MACRO. The ratio of the observed to the expected number of events integrated over all nadir angles is 0.73 ± .09 stat. ± .06 sys. ± .12 theor. . The flux of upgoing muons as a function of nadir angle is presented and compared to Monte Carlo expectations. At the 90% confidence level, the data are consistent with no neutrino oscillations or some possible oscillation hypothese with the parameters suggested by the Kamiokande contained-event analysis.

Abstract: Muon events collected with the streamer tube system of MACRO have been used to study the vertical muon intensity and to search for astrophysical point sources. New upper limits on the muon fluxes coming from source candidates have been obtained. The μ pair distance distribution and multimuon rates are presented and compared with Monte Carlo predictions for different primary cosmic rays composition models.

Abstract: A study of the primary cosmic ray composition in the energy range 5ṡ1014−5ṡ1015 eV is performed through the analysis of the deep underground muons and of the e.m. component of Extensive Air Showers detected in coincidence by the MACRO and EAS-TOP experiments at the Gran Sasso Laboratory. We conclude that: a) pure proton and Iron primary beams are excluded by the experimental data; b) a fraction of nuclei heavier than Helium is necessary to explain the experimental data both below and above the knee; c) a mixed composition, obtained a priori from extrapolations of the spectra directly measured below 100 TeV, yields a reasonable account of the observations up to the knee of the primary spectrum.

Abstract: Multimuon data from the MACRO experiment at Gran Sasso have been analysed using a new method which allows one to estimate the primary cosmic ray fluxes. The estimated all-particle spectrum is higher and flatter than the one obtained from direct measurements but is consistent with EAS measurements. The average mass number shows a weak dependence on the primary energy below 10^{6} GeV. Even within large uncertainties our data support a possible increase of the average mass number at higher energies.

Abstract: We have analyzed 44.3M single muons collected by MACRO from 1991 through 2000 in 2,145 live days of operation. We have searched for the solar diurnal, apparent sidereal, and pseudo-sidereal modulation of the underground muon rate by computing hourly deviations of the muon rate from 6 month averages. We find evidence for statistically significant modulations with the solar diurnal and the sidereal periods. The amplitudes of these modulations are, 18 pages, 8 of which are figures, 1 is a table.

Abstract: We present a study of the correlations in the arrival times of about 1016 single and multiple muons detected by the first two MACRO supermodules. The time correlations, from milliseconds to several hundrends of seconds, have been analyzed in terms of the random distribution, with which they are consistent. An analysis of the arrival times (up to 180 ns) of the muons from the same multimuon event is also given. © 1992.

Abstract: The angular distribution of upward-going muons produced by atmospheric neutrinos in the rock below the MACRO detector show anomalies in good agreement with two flavor neutrino-mu ==> neutrino-tau oscillations with maximum mixing and Delta m**2 around 0.0024 eV**2. Exploiting the dependence of magnitude of the matter effect on oscillation channel, and using a set of 809 upward-going muons observed in MACRO, we show that the two flavor neutrino-mu ==> neutrino-sterile oscillation is disfavored with 99% C.L. with respect to neutrino-mu ==> neutrino-tau., 7 pages 4 figures Submitted to Physics Letters B

Abstract: The MACRO underground experiment has started a systematic experimental study of the structure of a very high multiplicity event sample, with the aim of gaining a better understanding of the features of the high energy showers. We present here two new analyses: a) the analysis of the distribution of the separation between pairs of high multiplicity muons (''decoherence'' function); b) the search for clusters of muons within high multiplicity events. The first results are discussed together with a comparison between the real data and the Monte Carlo predictions.

Abstract: An analysis of the coincident deep underground muon data and of the e.m. component of Extensive Air Showers (EAS) as measured by the MACRO and EAS-TOP experiments at Gran Sasso is presented. Constraints on the primary cosmic ray composition are obtained, with the use of an interaction model that is based on collider data. The possibility of extrapolating the directly measured energy spectra to our energy range is tested.

Abstract: Recent results on muon astronomy from the MACRO experiment at Gran Sasso are presented. An analysis has been performed to search for astrophysical point sources of neutral particles which could produce energetic muons through interactions in the Earth's atmosphere. In this paper, we present results on an all-sky survey for an excess muon flux; searches for steady state and periodic muon signals from several candidate point sources; and a search for a short term variability in the muon flux from the direction of Cygnus X-3.

Abstract: We have developed and tested a transition radiation detector prototype suitable to measure the energy of muons in cosmic ray laboratories. The technical solutions adopted, based on extruded tubes as detectors and foam or fiber mats as radiators, allow to cover very large areas with a low number of channels and ensure stability of operation. Using an argon-carbon dioxide gas mixture it is possible to explore the muon energy range up to 1 TeV.

Abstract: The MACRO detector, located in the underground Gran Sasso Laboratory, had its initial data run from February 27 to May 30, 1989, using the first supermodule (SΩ∼800 m 2 sr ) . Approximately 245 000 muon events were recorded. Here are reported the results of the analysis of penetrating muons which determine the measured vertical muon flux at depths greater than 3000 m.w.e. In addition the data have been used to search for large scale anisotropies.

Abstract: Antineutrino interactions in BEBC are compared to look for differences between the differential cross sections per nucleon in neon and in deuterium. The identical geometries, beam spectra and muon identification criteria and acceptances allow comparison with very small systematic errors. The results are compared in detail with μ and e scattering data from EMC and SLAC. We find no rise in the ratio dσ/dx (ν Ne)/σ/dx (ν D2) at low x, independent of Q2 up to Q2 ∼ 14 GeV2. © 1984., 0, 58 auteurs, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: An event with the decay chain Σ c + → Λ c + + π 0 , Λ c + → K − + p + π + , has been observed in an exposure of BEBC, equipped with a track sensitive target, to the wide band neutrino beam from the SPS at CERN. The event has a unique three constraint kinematic fit to the ΔS = − ΔQ reaction v + p → μ − + p + K − + π + + π + + π 0 with both gammas from the π 0 decay detected. The proton and other final state particles are identified. The masses are M ( Λ c + ) = 2290 ± 3 MeV/ c 2 , M ( Σ c + ) = 2457 ± 4 MeV/ c 2 and M ( Σ c + ) − M ( Λ c + ) = 168 ± 3 MeV/ c 2 . Including other data one obtains M ( Σ c ++ ) − M ( Σ c + ) = 0 ± 4 MeV/ c 2 .

Abstract: Using a transition radiation detector we have neasured the energy of cosmicray muons in the Mont Blanc laboratory, where the NUSEX experiment is located. With this technique we have been able to cover linearly the energy range from 0.1 TeV to about 0.5 TeV, where the detector response begins to saturate. The measurements are consistent with a muon energy spectrum deduced from a E−3.71 distribution folded with 5000 hg/cm2 standard rock absorption.

Abstract: A study is presented of dimuon events from an exposure of BEBC to a wide band ν beam from the CERN SPS. These data double the available statistics on ν induced dilepton events observed in bubble chambers. The relative production rate and V0 yield have been measured and found to agree with previous experiments. The analysis of several kinematical variables shows that the gros features of the data agree with the predictions of the GIM model. Some indication exists that part of the signal could be due to quasi elastic production of the “beautiful baryon”, but the statistical significance is too weak to draw definitive conclusions. © 1980, All rights reserved., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: The MACRO detector is presently under construction, its installation at Gran Sasso being planned to start in September 1987. It is a large area detector, the acceptance for isotropic particle fluxes being around 10 000 m 2 sr, designed to search for rare phenomena in the cosmic radiation. It makes use of three detection techniques: liquid scintillator counters, plastic streamer tubes, and track-etch. It will perform a search for GUT monopoles (or any supermassive charged penetrating particle), a survey of cosmic point sources of HE gammas and neutrinos, a systematic study of the penetrating cosmic ray muons, and will be sensitive to neutrino bursts from gravitational stellar collapses in the Galaxy.

Abstract: Comparing the kinematical distributions of events obtained on neon and deuterium targets in similar experimental conditions reveals a reduction of the neutrino and antineutrino charged current cross section per nucleon in neon at low Q 2 . The effect, interpreted as due to geometric shadowing of the weak propagator in interactions of neutrinos and antineutrinos with nuclei, agrees well with predictions derived from PCAC.

Abstract: An attempt at the direct observation of the cascade decay of beauty particles, produced by π- of 350 GeV/c leading to 3 muons or 4 muons in the final state, has been made in an emulsion/counter hybrid experiment at CERN. Under the assumption that the lifetime of beauty particles is of the order of 10-13s the non-observation of any candidates provides an upper limit for beauty production of ∼90 nb at the 90% confidence level., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: An exposure of BEBC equipped with the hydrogen-filled TST to the v μ wide band beam at the CERN SPS has been used to study v μ interactions on free protons. About neutral induced interactions have been observed inside the hydrogen and separated into charged current, neutral current and neutral hadron interactions using a multivariate discriminant analysis based on the kinematics of the events. The neutral to charged current cross-section ratio has been determined to be R p v = 0.33 ± 0.04. When combined with the value of R p v previously determined in the same experiment, the result is compatible with the prediction of the standard SU (2) × U (1) model for sin 2θ W = 0.24 -0.08 +0.06 and ρ = 1.07 -0.08 +0.06. Fixing the parameter ρ = 1 yields sin 2θ W = 0.18 ± 0.04., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: BEBC filled in turn with hydrogen, and with a neon-hydrogen mixture, was exposed to the CERN SPS wide band neutrino and antineutrino beams. The ratios of the charged-current cross sections per nucleon, σ(νH2) σ(νNe) and σ(νH2) σ(νNe), between 20 and 300 GeV were found to be 0.656 ± 0.020 and 1.425 ± 0.052, respectively. Multiplying these ratios by the revised cross sections in neon, σ(νNe) E = (0.723 ± 0.038) × 10-38 cm2/GeV per nucleon and σ(νNe) E = (0.351 ± 0.019) × 10-38 cm2/GeV per nucleon, and their ratio, σ(νNe) σ(νNe) = 0.485 ± 0.020, yields values for the total charged-current cross sections on protons, σ(νp)/E and σ(νp) E, of (0.474 ± 0.029) × 10-38 cm2/GeV and (0.500 ± 0.032) × 10-38 cm2/GeV. respectively, and a value for the ratio σ(νp) σ(νp) of 1.053 ± 0.066. © 1986., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: In this paper, the first of a two-part work, we present the reconstruction and measurement of muon events detected underground by the MACRO experiment at Gran Sasso (E{sub {mu}}{ge} 1.3 TeV in atmosphere). The main aim of this work is to discuss the muon multiplicity distribution as measured in the detector. The data sample analyzed consists of 4.4{times}10{sup 6} muon events, of which {approximately} 263000 are multiple muons, corresponding to a total live time of 5850 h. In this sample, the observed multiplicities extend above N{sub {mu}}=35, with intermuon separations up to 50 m and beyond. Additional complementing measurements, such as the inclusive muon flux, the angular distribution, and the muon separation distribution (decoherence), are also included. The physical interpretation of the results presented here is reported in the following companion paper. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: A transition radiation detector module, 6 × 2 × 2 m3 in size, has been developed, tested and then installed on the MACRO detector at the Gran Sasso National Laboratory. The modular structure consisting of proportional tubes interleaved with polyethylene foam radiators allows to cover a large area. This detector measures the residual energies, up to 1 TeV, of penetrating muons. We discuss the possibility to obtain more physical information from these muons by measuring their residual energy and the performances of the first module. Calibration results of prototypes operated in a test beam at the CERN P.S. are also given.

Abstract: The half of the MACRO detector, a large area Monopole, Astrophysics, Cosmic Ray Observatory is nearly completed in Hall B of the Gran Sasso Laboratory. One supermodule is already taken data and the remainder will be activated in few months. A general overview of the MACRO detector, together with its physics capabilities as far as the search for point sources of high energy neutrino is concerned, will be presented.
