Abstract

A high-density calorimeter, consisting of magnetized iron planes interleaved by RPCs, as tracking and timing devices, is a good candidate for a next generation experiment on atmospheric neutrinos. With 34 kt of mass and in four years of data taking, this experiment will be sensitive to $\nu_\mu \to \nu_x$ oscillation with $\Delta m^2 > 6 \times 10^{-5}$ and mixing near to maximal and fully cover the region of oscillation parameters suggested by Super-Kamiokande results. Moreover, the experimental method will enable to measure the oscillation parameters from the modulation of the L/E spectrum ($\nu_\mu$ disappearance). For $\Delta m^2 > 3 \times 10^{-3}$ eV$^2$, this experiment can also establish whether the oscillation occurs into a tau or a sterile neutrino, by looking for an excess of muon-less events at high energies produced by upward-going tau neutrinos ($\nu_\tau$ appearance)., Comment: 12 pp., 5 figg., paper contributed to Lepton-Photon 99

Abstract

We report on an R&D program targeted to produce large area glass resistive plate chamber (RPC) detectors. The aim of this work has been to exploit as much as possible glass industry standard techniques. One of the most important steps we have introduced to reach the goal of fully automated production of large area detectors has been the use of screen silk printing technique for the resistive electrodes. A substantial number of prototypes detector have been produced: [approximately equal to]100 [m.sup.2]. The detector's efficiency as a function of the local particle rate has been tested at the DAFNE Beam Test Facility with 500 MeV electrons. Results concerning long term stability tests, presently going on by means of two cosmic ray telescopes in two different laboratories, will also be presented. Index Terms--Ageing, glass, rate capability, resistive plate chamber (RPC).

Abstract

We discuss the final results of the MACRO experiment on atmospheric neutrino oscillations. The data concern event topologies with average neutrino energies of ~3 and ~50 GeV. Multiple Coulomb Scattering of the high energy muons was used to estimate the neutrino energy event by event. The angular distributions, the L/E_nu distribution, the particle ratios and the absolute fluxes all favor nu_mu --> nu_tau oscillations with maximal mixing and Delta m^2 ~0.0023 eV^2. Emphasis is given to measured ratios which are not affected by Monte Carlo (MC) absolute normalization; a discussion is made on MC uncertainties. A preliminary search for possible Lorentz invariance violation contributions to atmospheric neutrino oscillations is presented and discussed., 4 pages, 6 figures.

Abstract

The MACRO experiment detected different categories of atmospheric muon neutrinos. We describe in this paper the energy estimate of upward throughgoing muons by using the multiple coulomb scattering. Combining the results of such analysis with the upgoing muon angular distribution, both not using the absolute ν flux normalization informations, an evidence above 4σ for atmospheric neutrino oscillation is found.

Abstract

In the MACRO experiment the flux of atmospheric muon neutrinos has been studied through the detection of upward-going muons generated in the rock below the detector and also through neutrino interactions inside the apparatus. Several topologies of neutrino events have been detected, which correspond to different neutrino parent energies. The measured flux in the different data sets shows a deficit with respect to the Monte Carlo predictions. Moreover, the upward-throughgoing muon sample (median neutrino energy ∼ 50 GeV ) also shows a distortion in the angular distribution shape. Interpreted in terms of neutrino oscillation, these results favor a ν μ into ν τ oscillation scenario, while the ν μ into ν sterile channel is disfavared at 99% C.L.

Abstract

A measurement of the flux of neutrino-induced muons using the MACRO detector is presented. Different event topologies, corresponding to different neutrino parent energies can be detected. The upward throughgoing muon sample is the larger event sample. The observed upward-throughgoing muons are 26% fewer than expected and the zenith angle distribution does not fit with the expected one. Assuming neutrino oscillations, both measurements suggest maximum mixing and Dm2 of a few times 10-3 eV2. The other samples are due to the internally produced events and to upward-going stopping muons. These data show a regular deficit of observed events in each angular bin, as expected assuming neutrino oscillations with maximum mixing, in agreement with the analysis of the upward-throughgoing muon sample., Comment: 7 pages 6 figures to appear in the proceedings of XVIII International Conference on Neutrino Physics and Astrophysics (Neutrino'98), Takayama, Japan 4-9 June, 1998

Abstract

High energy neutrinos from astrophysical sources can be detected as upward-going muons produced in charged-current interactions with the matter surrounding the detector. We present the results of a search for either a diffuse astrophysical neutrino flux or a point-like source of neutrinos in the sample of upward-going muons gathered by MACRO. We find no evidence for both signals. The muon flux upper limit for the diffuse signal has been set at the level of 1.7 × 10^-14cm^-2 s^-1 sr^-1.

Abstract

We report the analysis of the N ϵ - N μ coincident events collected by the MACRO/EAS-TOP collaboration at the Gran Sasso Laboratories. The result points to a primary composition becoming heavier around the knee of the primary spectrum (in the energy region 10 15 – 10 16 eV). The result is in very good agreement with the measurements of EAS-TOP alone at the surface, wich detects muons with energy E μ > 1 GeV and uses the same (QGSJET) interaction model.

Abstract

The final results of the MACRO experiment on atmospheric neutrino oscillations are presented and discussed. The data concern different event topologies with average neutrino energies of ~3 and ~50 GeV. Multiple Coulomb Scattering of the high energy muons in absorbers was used to estimate the neutrino energy of each event. The angular distributions, the L/E_nu distribution, the particle ratios and the absolute fluxes all favour nu_mu --> nu_tau oscillations with maximal mixing and Delta m^2 =0.0023 eV^2. A discussion is made on the Monte Carlos used for the atmospheric neutrino flux. Some results on neutrino astrophysics are also briefly discussed., Invited Paper at the NANP03 Int.

Abstract

The final results of the MACRO experiment on atmospheric neutrino oscillations are presented. The data concern different event topologies with average neutrino energies of ~ 3 and ~ 50 GeV. Multiple Coulomb Scattering of the high energy muons was used to estimate the neutrino energy event by event. The angular distributions, the L/E_nu distribution, the particle ratios and the absolute fluxes all favour nu_mu --> nu_tau oscillations with maximal mixing and Delta m^2 ~ 0.0023 eV^2. Emphasis is given to measured ratios which are not affected by Monte Carlo (MC) absolute normalization; a discussion is made on MC uncertainties., 3 pages, 6 figures, paper presented at the HEP EPS Conf., Aachen, Germany, July 2003 Added references (19/08/2004)

Abstract

We have measured directly the residual energy of cosmic ray muons crossing the MACRO detector at the Gran Sasso Laboratory. For this measurement we have used a transition radiation detector consisting of three identical modules, each of about 12 m(2) area, operating in the energy region from 100 GeV to 1 TeV, The results presented here were obtained with the first module collecting data for more than two years. The average single muon energy is found to be 320 +/- 4 (stat.) +/- 11 (syst.) GeV in the rock depth range 3000-6500 hg/cm(2). The results are in agreement with calculations of the energy loss of muons in the rock above the detector. (C) 1999 Elsevier Science B.V.

Abstract

The contemporaneous measurement of TeV muons in deep underground laboratories and of the e.m. component at the surface allows checking the hadron interaction models and the propagation codes used in EAS experiments in a primary energy range 10–50 TeV in which the primary spectra are measured by direct experiments. First results of such measurements between MACRO and EAS-TOP at the Gran Sasso laboratory, in this energy range, are here reported.

Abstract

Since the last presentation to the SPSC committee, the ICARUS T600 detector assembly has progressed up to its completion. The cryogenic plant, the liquefier system, the read-out, the Laboratory infrastructure and the safety facilities have been installed. However the Collaboration had to face some problems that have delayed the start-up of the commissioning of the apparatus. Besides the one-month suspension of the activities in the Laboratory, following the seismic event in the l’Aquila region, delays have emerged due to the commissioning of the liquefier system, to the pressure/vacuum leaking of some wire signal feed-through flanges and to the deformation of a panel of the external thermal insulation.

Abstract

The MACRO underground experiment performed a systematic experimental study of muon bundle structure. The aim is to gain a better understanding of the features of high energy cosmic ray interactions. The reliability of the hadronic interaction model in reproducing the shower development features at the highest energy can be studied selecting high multiplicity muon bundles. We present here the analisys of the muon lateral distribution (decoherence function) based on two different method( detector dependent and detector independent method), the decoherence function in a high multiplicity event subsample and the search for muon clusters.

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 +/- 0.05 for E < 500 TeV and 2.9 +/- 0.3 for E > 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 +/- 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 similar to 50 TeV up to several thousand TeV.

Abstract

The analysis of the e.m. component of EAS and of the deep underground muons detected in coincidence by EAS-TOP and MACRO has been performed to study the primary cosmic ray composition in the energy range 5 · 1014 − 1 · 1016eV, around the knee of the primary spectrum. New results are presented with improved statistics, mostly above the knee of the energy spectrum.

Abstract

The vertical muon intensity measured with MACRO at the Gran Sasso Laboratory, in the depth range 3200-7000 hg cm(-2) of standard rock, corresponding to 2-200 TeV/nucleon primary energy range, is presented. An estimation of the muon energy spectrum at the surface will also be shown. The results will be compared with those of other experiments and with the computation of the intensities obtained using a full Monte Carlo calculation with different hypotheses for the primary cosmic ray composition.

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

The MACRO detector is sensitive to wide range of ionizing massive particles in cosmic rays. These include “nuclearites” or strange quark matter. The negative result of a search lasting about 20 months using 1/12 of the detector has yielded a flux limit of 1.1 × 10{−14}cm{−2}sr{−1}s{−1} for strange matter with mass 10{−10}g < m < 0.1 g. For m > 0.1g, the limit is 5.5 × 10{−15}cm{−2}sr{−1}s{−1}. Since the velocity range of nuclearites to which MACRO is sensitive extends down to near the escape velocity of the earth, the flux limit not only applies to nuclearites of galactic or extra-galactic origin but also applies to nuclearites that are trapped in the solar system.
