Abstract

The nuclear emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS of 27 GeV average neutrino energy from 1994 to 1997. In total about 100000 charged-current neutrino interactions with at least one identified muon were located in the emulsion target and fully reconstructed, using newly developed automated scanning systems. Charmed particles were searched for by a program recognizing particle decays. The observation of the decay in nuclear emulsion makes it possible to select a sample with very low background and minimal kinematical bias. 2013 charged-current interactions with a charmed hadron candidate in the final state were selected and confirmed through visual inspection. The charm production rate induced by neutrinos relative to the charged-current cross-section is measured to be sigma(nu_mu N -> mu- C X)/sigma(CC) = (5.75 +-0.32 stat +-0.30 syst)%. The charm production cross-section as a function of the neutrino energy is also obtained. The results are in good agreement with previous measurements. The charm-quark hadronization produces the following charmed hadrons with relative fractions (in %): f_Dzero = 43.7+-4.5, f_Lambda_c^plus = 19.2+-4.2, f_Dplus = 25.3+-4.2, and f_D_splus = 11.8+-4.7., Comment: 16 pages, 5 figures

Abstract

During the years 1994-1997, the emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS collecting about 10 6 neutrino interactions. A measurement of ?¯µ-induced charm production is performed by using the presence of a 5% ?¯µ component in the ?µ beam. The measurement takes advantage of the capability to observe the decay topology in the emulsion. The analysis is based on a sample of charged-current interactions with at least one identified muon. About 100000 were located in the emulsion target and fully reconstructed. By requiring a positive muon charge as determined by the CHORUS muon spectrometer, 32?¯µ-induced charm events were observed with an estimated background of 3.2 events. At an average antineutrino energy in the neutrino beam of 18 GeV, the charm production rate induced by antineutrinos is measured to be ?(?¯µN›µ+c¯X)/?(?¯µN›µ+X) =(5.0-0.9+1.4(stat)±0.7(syst))%. The ratio between neutral and charged charm production rates in this process is (2.6-1.0+1.7(stat)±0.8(syst)). The charm production rate as a function of the antineutrino energy is found to be in good agreement with previous results derived from di-lepton data. © 2004 Elsevier B.V. All rights reserved.

29. Study of the Electromagnetic Environment in Electrified Railroad Sections.

Author

Bestem'yanov, P. F., Kravtsov, Yu. A., and Shamanov, V. I.

Abstract

Systems of monitoring railroad sections for freeness, as well as systems of transferring information along the rails to train locomotives and between signal points of automatic blocking, operate in a complex electromagnetic environment, especially in electric propulsion sections. The equipment of these systems is affected by electromagnetic interferences in a multifactorial manner, and the causes of high-level interferences are numerous and often interrelated. The tasks one has to perform while studying the electromagnetic environment are fixing a random interference generation process, processing the array of results, and identifying the causes of interferences. The first task can be accomplished by means of digital multichannel oscilloscope recorders, as well as various kinds of current- or voltage-measuring sensors. Accomplishing the second task depends on the goal and becomes very difficult due to the multifactorial essence of interference generation. The studies were pursued in various conditions, including high-speed Sapsan train traffic sections, subway train traffic sections, and heavy train traffic sections. Mathematical descriptions are derived as the probability distribution density for several kinds of electromagnetic interference. [ABSTRACT FROM AUTHOR]

Abstract

A relative measurement of total cross-sections is reported for polyethylene, marble, iron, and lead targets for the inclusive charged-current reaction nu(mu) + N --> mu- + X. The targets, passive blocks of similar to100 kg each, were exposed simultaneously to the CERN SPS wide-band muon-neutrino beam over a period of 18 weeks. Systematic effects due to differences in the neutrino flux and detector efficiency for the different target locations were minimised by changing the position of the four targets on their support about every two weeks. The relative neutrino fluxes on the targets were monitored within the same experiment using charged-current interactions in the calorimeter positioned directly downstream of the four targets. From a fit to the Z/A dependence of the total cross-sections a value is deduced for the effective neutron-to-proton cross-section ratio.

Abstract

The nuclear emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS of 27 GeV average neutrino energy from 1994 to 1997. In total about 100000 charged-current neutrino interactions with at least one identified muon were located in the emulsion target and fully reconstructed, using newly developed automated scanning systems. Charmed particles were searched for by a program recognizing particle decays. The observation of the decay in nuclear emulsion makes it possible to select a sample with very low background and minimal kinematical bias. 2013 charged-current interactions with a charmed hadron candidate in the final state were selected and confirmed through visual inspection. The charm production rate induced by neutrinos relative to the charged-current cross-section is measured to be sigma(nu_mu N -> mu- C X)/sigma(CC) = (5.75 +-0.32 stat +-0.30 syst)%. The charm production cross-section as a function of the neutrino energy is also obtained. The results are in good agreement with previous measurements. The charm-quark hadronization produces the following charmed hadrons with relative fractions (in %): f_Dzero = 43.7+-4.5, f_Lambda_c^plus = 19.2+-4.2, f_Dplus = 25.3+-4.2, and f_D_splus = 11.8+-4.7., 16 pages, 5 figures

Abstract

During the years 1994-97, the emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS of 27 GeV average neutrino energy. In total about 100 000 charged-current neutrino interactions were located in the nuclear emulsion target and fully reconstructed. From this sample of events which was based on the data acquired by new automatic scanning systems, 1048 charged-current interactions with a D^0 in the final state were selected by a pattern recognition program and confirmed as neutral-particle decays through visual inspection. The ratio of decay branching fractions of the D^0 into four-charged particles to two charged particles was measured to B(D^0 -> V4) / B(D^0 -> V2) = 0.207+- 0.004. The inclusive measurement of the observed production rate of the D^0 with a decay into four charged prongs in combination with external measurements of this topological branching ratio was used to determine the total D^0 production rate by neutrinos without additional assumption on the branching fractions. The value of this rate relative to the charged-current cross-section was found to be \sigma(D^0) / \sigma(CC) = 0.0269 +- 0.0018 +- 0.0013. In addition, the same normalization method was used to deduce the inclusive topological decay rate into final states with neutral particles only. A value of 0.218 +- 0.049 +- 0.036 was found for this branching fraction. From an observed number of three charged six-prongs events the branching ratio into six charged particles was determined to be (1.2^1.3_-0.9 +- 0.2) x 10^-3. A measurement of the energy dependence of the D^0 production by neutrinos relative to the total charged-current cross-section is also reported. This measurement was used to deduce for m_c, the effective charm-quark mass, a value of (1.42 +- 0.08) GeV/c^2.

Abstract

During the years 1994-1997, the emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS. In total about 100 000 charged-current neutrino interactions were located in the nuclear emulsion target and fully reconstructed. From this sample of events which was based on the data acquired by new automatic scanning systems, 1048 D0 events were selected by a pattern recognition program. They were confirmed as neutral-particle decays through visual inspection. Fragmentation properties of deep-inelastic charm production were measured using these events. Distributions of the D0 momentum, Feynman x (xF), z and tan?out, the transverse angle out of the leptonic plane defined by the muon and the neutrino, are presented. The mean value of z was measured to be =0.63±0.03(stat)±0.01(syst). From fits to the z distribution, values for the Peterson parameter ?P=0.108±0.017(stat) ±0.013(syst) and the Collins-Spiller parameter ?CS=0.21-0.04+0. 05(stat)±0.04(syst) are found. For the average value of xF we find =0.38±0.04(stat)±0.03(syst) and for the forward-backward asymmetry A=0.79±0.14(stat)±0.05(syst). The distribution of tan?out was measured with an average value =0.030±0.002. © 2004 Elsevier B.V. All rights reserved.

Abstract

A measurement of $\Lambda_c^+$ production in neutrino nucleon charged-current interactions is presented. In a sub-sample of about 50 000 interactions located in the emulsion target of the CHORUS detector exposed to the wide band neutrino beam of the CERN SPS, candidates for decays of short lived particles were identified using new automatic scanning systems and later confirmed through visual inspection. Criteria based on the flight length allowed a statistical separation among the different charm species thus enabling a sample particularly rich in $\Lambda_c^+$ to be defined. At an average neutrino energy of $27$ \GeV, the product ${\sigma(\Lambda_c^+)}/{\sigma(CC)} \times BR(\Lambda_c^+ \rightarrow 3p) $ was measured to be $(0.37 \pm 0.10(stat) \pm 0.02(syst) ) \times 10^{-2}$, while the values of $(1.54\pm0.35(stat)\pm0.18(syst) ) \times 10^{-2} $ and of $0.24 \pm 0.07(stat) \pm 0.04(syst)$ were obtained for ${\sigma(\Lambda_c^+)}/{\sigma(CC)}$ and $BR(\Lambda_c^+ \rightarrow 3p)$ respectively.

Abstract

We report on the first direct observation of a neutrino induced charged-current interaction with two subsequent decays of short-lived particles close to the interaction vertex. This rare double- kink signature in the CHORUS emulsion target is interpreted as a $D_s^{*+}$ production followed by the decay chain $D_s^{*+} \rightarrow D_s^+ \gamma, D_s^+ \rightarrow \tau^+ \nu_\tau ,$ \linebr eak $\tau^+\rightarrow \mu^+\nu_\mu\bar{\nu_\tau}$. The event is characterised by small $Q^2$ and small four-momentum transfer squared $t$ to the target nucleon, which indicates a diffractive pr oduction mechanism. A complete analysis of the event is presented.

Abstract

Part of the neutrino events collected in 1994-1995 by the CHORUS experiment has been analysed. A search was performed for $\nu_{\tau}$ charged current interactions followed by the $\tau$ lepton deca y into a single charged negative hadron, a possible indication for $\numtonut$ oscillation. A sample of 6,844 events without an identified muon has been located in the emulsion target. Within the s election criteria, no $\tau^-$ candidate has been found. Combining this result with the one from the search for $\nu_\tau$ interactions using the muonic decay mode (36,182 events with an identified muon), a 90\% C.L. limit on the mixing angle $\sin2t < 1.8\cdot 10^{-3}$ (at large $\Delta m^2$) has been derived.
