Abstract: The local hadronic calibration scheme developed for the reconstruction and calibration of jets and missing transverse energy in ATLAS has been evaluated using data obtained during combined beam tests of modules of the ATLAS liquid argon endcap and forward calorimeters. These tests covered the pseudorapidity range of 2.5 | η | 4.0 . The analysis has been performed using special sets of calibration weights and corrections obtained with the G eant 4 simulation of a detailed beam-test setup. The evaluation itself has been performed through the careful study of specific calorimeter performance parameters such as e.g. energy response and resolution, shower shapes, as well as different physics lists of the G eant 4 simulation.

Abstract: The pseudorapidity region 2.5 | η | 4.0 in ATLAS is a particularly complex transition zone between the endcap and forward calorimeters. A set-up consisting of 1 4 resp. 1 8 of the full azimuthal acceptance of the ATLAS liquid argon endcap and forward calorimeters has been exposed to beams of electrons, pions and muons in the energy range E ⩽ 200 GeV at the CERN SPS. Data have been taken in the endcap and forward calorimeter regions as well as in the transition region. This beam test set-up corresponds very closely to the geometry and support structures in ATLAS. A detailed study of the performance in the endcap and forward calorimeter regions is described. The data are compared with MC simulations based on GEANT 4 models.

Abstract: The final oscillation analysis of the complete set of data collected by CHORUS in the years 1994-1997 is presented. Reconstruction algorithms of data extracted by electronic detectors were improved and the data recorded in the emulsion target were analysed by new automated scanning systems, allowing the use of a new method for event reconstruction in emulsion. CHORUS has applied these new techniques to the sample of 1996-1997 events for which no muons were observed in the electronic detectors. Combining the new sample with the data analysed in previous papers, the overall sensitivity of the experiment to the ?? appearance is thus improved. In a two-neutrino mixing scheme, a 90% C.L. upper limit of sin2 2 ?µ ? < 4.4 × 10-4 is set for large ? m2, improving by a factor 1.5 the previously published CHORUS result. © 2007 Elsevier B.V.

Abstract: A new search for decays of heavy isosinglet neutrinos produced by neutral-current neutrino interactions in the CERN wide-band neutrino beam has been conducted by the CHARM-II Collaboration. We searched for heavy neutrinos created by scattering muon neutrinos on nucleons and decaying into μ + μ − ν μ . Production and decay of heavy neutrinos would appear as double events in the detector. Each double event candidate was tested wheather the measured quantities are compatible with the kinematics of this process. No event passed this test. The analysis is based on 2 × 10 7 neutral-current neutrino events collected from 1987–1991. The experiment is sensitive to heavy neutrinos in the mass range 0.3–2.4 GeV/ c 2 . The best limit for the mixing parameter is | U μi | 2 −5 for a mass around 2 GeV/ c 2 . The analysis improve order of magnitude previous results derived from wide-band neutrino beam exposures of the CHARM detector.

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 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 be B ( D 0 → V 4 ) / B ( D 0 → V 2 ) = 0.207 ± 0.016 ± 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 σ ( D 0 ) / σ ( 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-prong events the branching ratio into six charged particles was determined to be ( 1.2 −0.9 +1.3 ± 0.2 ) × 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 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. A high-statistics sample of neutrino interactions with a D 0 in the final state was collected. Using the decay mode D * + → D 0 π + a production cross-section measurement of the D * + in neutrino–nucleon charged-current interactions was performed. The low Q-value of the decay was used to isolate a sample of candidate events containing a positive hadron with a small p T with respect to the D 0 direction. A signal of 22.1 ± 5.5 D * + events was obtained. The D * + production cross-section relative to the D 0 production cross-section, σ ( D * + ) / σ ( D 0 ) , was estimated to be 0.38 ± 0.09 ( stat ) ± 0.05 ( syst ) . From this result, the fraction of D 0 's produced via the decay of a D * was deduced to be 0.63 ± 0.17 . The D * + production cross-section relative to the ν μ charged-current interaction, σ ( D * + ) / σ ( CC ) , was estimated to be [ 1.02 ± 0.25 ( stat ) ± 0.15 ( syst ) ] % .

Abstract: We report new constraints on the existence of additional Z bosons derived from neutrino-electron scattering data. The analysis is based on data taken by the CHARM II Collaboration during five years of exposure of the detector to the wide band neutrino beam at CERN. The limits on the mass of these new particles are evaluated in the framework of E 6 superstring-inspired theories and Left-Right symmetric models. Limits on the so-called Z 1 are also reported.

Abstract: We present a leading order QCD analysis of a sample of neutrino induced charged-current events with two muons in the final state originating in the lead-scintillating fibre calorimeter of the CHORUS detector. The results are based on a sample of 8910 neutrino and 430 antineutrino induced opposite-sign dimuon events collected during the exposure of the detector to the CERN Wide Band Neutrino Beam between 1995 and 1998. The analysis yields a value of the charm quark mass of mc = (1.26 ± 0.16 ± 0.09) GeV / c2 and a value of the ratio of the strange to non-strange sea in the nucleon of κ = 0.33 ± 0.05 ± 0.05, improving the results obtained in similar analyses by previous experiments. © 2008 Elsevier B.V.

Abstract: The CHORUS experiment, designed to search for $\nu_{\mu}\to\nu_{\tau}$ oscillations, consists of a nuclear emulsion target and electronic detectors. In this paper, results on the production of charged particles in a small sample of charged-current neutrino-- and anti-neutrino--nucleus interactions at high energy are presented. For each event, the emission angle and the ionization features of the charged particles produced in the interaction are recorded, while the standard kinematic variables are reconstructed using the electronic detectors. The average multiplicities for charged tracks, the pseudo-rapidity distributions, the dispersion in the multiplicity of charged particles and the KNO scaling are studied in different kinematical regions. A study of quasi-elastic topologies performed for the first time in nuclear emulsions is also reported. The results are presented in a form suitable for use in the validation of Monte Carlo generators of neutrino--nucleus interactions., Comment: 17 pages, 5 figures

Abstract: In this paper a search for associated charm production both in neutral and charged current $\nu$-nucleus interactions is presented. The improvement of automatic scanning systems in the {CHORUS} experiment allows an efficient search to be performed in emulsion for short-lived particles. Hence a search for rare processes, like the associated charm production, becomes possible through the observation of the double charm-decay topology with a very low background. About 130,000 $\nu$ interactions located in the emulsion target have been analysed. Three events with two charm decays have been observed in the neutral-current sample with an estimated background of 0.18$\pm$0.05. The relative rate of the associated charm cross-section in deep inelastic $\nu$ interactions, $\sigma(c\bar{c}\nu)/\sigma_\mathrm{NC}^\mathrm{DIS}= (3.62^{+2.95}_{-2.42}({stat})\pm 0.54({syst}))\times 10^{-3}$ has been measured. One event with two charm decays has been observed in charged-current $\nu_\mu$ interactions with an estimated background of 0.18$\pm$0.06 and the upper limit on associated charm production in charged-current interactions at 90% C.L. has been found to be $\sigma (c\bar{c} \mu^-)/\sigma_\mathrm{CC} < 9.69 \times 10^{-4}$., Comment: 10 pages, 4 figures

Abstract: After completion of the data taking for the ?µ›?? oscillation search, the CHORUS lead-scintillator calorimeter was used in the 1998 run as an active target. High-statistics samples of charged-current interactions were collected in the CERN SPS west area neutrino beam. This beam contained predominantly muon (anti-)neutrinos from sign-selected pions and kaons. We measure the flux and energy spectrum of the incident neutrinos and compare them with beam simulations. The neutrino-nucleon and anti-neutrino-nucleon differential cross-sections are measured in the range 0.01

Abstract: Part of the neutrino events collected in 1994-1995 by the CHORUS experiment has been analysed. A search was performed for ντ charged current interactions followed by the τ lepton decay into a single charged negative hadron, a possible indication for νμ→ντ oscillation. A sample of 6844 events without an identified muon has been located in the emulsion target. Within the selection criteria, no τ− candidate has been found. Combining this result with the one from the search for ντ interactions using the muonic decay mode (36 182 events with an identified muon), a 90% C.L. limit on the mixing angle sin22θμτ

Abstract: A measurement of ?c+ production in neutrino nucleon charged-current interactions is presented. In a subsample 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 A+ to be defined. At an average neutrino energy of 27 GeV, the product ?(?c+)/?(CC) × BR(?c+ › 3p) was measured to be (0.37 ± 0.10(stat) ± 0.02(syst)) × 10-2, while the values of (1.54 ± 0.35(stat) ± 0.18(syst)) × 10-2 and of 0.24 ± 0.07(stat) ± 0.04(syst) were obtained for ?(?c+)/?(CC) and BR(?c+ › 3p), respectively. © 2003 Elsevier Science B.V.

Abstract: The fine granularity of the CHARM-II detector has been exploited to search, in the CERN-SPS wide band neutrino beam, for quasi-elastic ντ interactions followed by the decay τ → πντ. Since the sampling thickness of the target calorimeter corresponds to ∼ 1 9 of an interaction length, these events appear in the detector as a single track followed by a hadronic shower. The study of the “single pion” events is used to set limits on the νμ → ντ oscillation parameters. The maximum sensitivity to the mixing angle θ is reached for Δm2 = 50 eV2 allowing to exclude values of sin22θ greater than 6.4 × 10−3 at 90% CL.

Abstract: CHORUS is an experiment searching for nu(mu) --> nu(tau) oscillation in the CERN wide band neutrino beam with a hybrid setup consisting of a nuclear emulsion target followed by electronic detectors. The experiment has been taking data from 1994 through 1997. A subset of the neutrino interactions collected in 1994 and 1995 have been analyzed, looking for nu(tau) charged current interactions where the tau lepton decays to mu(mu)nu(tau). In a sample of 31,423 nu(mu) charged current interactions, no nu(tau) candidates were found. For large Delta m(mu tau)(2) values, a limit on the mixing angle of sin(2)2 theta(mu tau) < 3.5 x 10(-3) at 90% C.L. can be set, thus improving the previous best result.

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*(+) --> D-s(+) gamma, D-s(+) --> tau(+) v(tau),tau(+) --> mu(+) v(mu)v(tau). The event is characterised by small Q(2) and small four-momentum transfer squared t to the target nucleon, which indicates a diffractive production mechanism. A complete analysis of the event is presented. (C) 1998 Elsevier Science B.V. All rights reserved.

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 decay into a single charged negative hadron, a possible indication for nu(mu) --> nu(tau) oscillation. A sample of 6844 events without an identified muon has been located in the emulsion target. Within the selection criteria, no tau(-) candidate has been found. Combining this result with the one from the search fur nu(tau) interactions using the muonic decay mode (36182 events with an identified muon), a 90% C.L. limit on the mixing angle sin(2)2 theta(mu tau) < 1.8.10(-3) (at large Delta m(2)) has been derived.

Abstract: We report our final results from the analysis of the full high statistics sample of events of the reaction \imd\,\, collected with the \CHARMII{} detector in the CERN wide-band neutrino beam during the years 1988 to~1991. From a signal of 15,758 \pm 324 inverse muon decay events we derived, in the Born approximation, a value of (16.51 \pm 0.93) \times 10^{-42} \unit{cm}^2 \unit{GeV}^{-1} for the asymptotic cross section slope \sigma/E_\nu, in good agreement with the Standard Model prediction of 17.23 \times 10^{-42} \unit{cm}^2 \unit{GeV}^{-1}. The result constrains the scalar coupling of the electron and the muon to |\gLL{S}|^2 < 0.475\ \rm{at}\ 90\%\ \rm{CL}.

Abstract: We report new bounds on electromagnetic properties of the muon neutrino obtained from a study of neutrino-electron scattering. The results are based on the analysis of differential cross section data collected with the CHARM II detector. The 90% C.L. limit on the magnetic moment of the muon-neutrino mu(nu mu) < 3 . 10(-9) mu(B) confirms limits obtained at much lower energies. The limit on the anomalous charge radius of the muon neutrino \[r(2)]anom\ < 6.0 . 10(-33) cm(2) improves earlier results by nearly a factor three.

Abstract: A search for upsilon(mu) --> upsilon(e) and ($) over bar upsilon(mu) --> ($) over bar upsilon(e) oscillations has been carried out with the CHARM LI detector exposed to the CERN wide band neutrino beam. The data were collected over five years, alternating beams mainly composed of muon-neutrinos and muon-antineutrinos. The number of interactions of upsilon(e) and ($) over bar upsilon(e) observed is comparable with the number of events expected from flux calculations. For large squared mass differences the upper limits obtained on the mixing angle are sin(2)2 theta < 9.4.10(-3) for upsilon(mu) oscillating to upsilon(e) and sin(2)2 theta < 4.8.10(-3) for ($) over bar upsilon(mu) to ($) over bar upsilon(e) at the 90% confidence level. Combining neutrino and antineutrino data the upper limit is 5.6.10(-3).

Abstract: WOS: 000223122600006 This Letter reports on a study of trimuon events induced by neutrino interactions in the CHORUS calorimeter exposed to the CERN SPS wide-band v(mu) beam. Among the multimuon events produced in the calorimeter, 42 mu(-) mu(-) mu(+) events were selected and their kinematical properties investigated. In the past, several groups collected a sample of about one hundred events of this type but their source was largely unknown. Taking advantage of experimental data presently available on the production and muonic branching ratios of light neutral mesons and resonances, we make absolute predictions for the expected rates in our experiment. Detailed Monte Carlo simulations described in this article show that more than half of the trimuon events can be attributed to this source. Muons from pi- and K- decays in charm dimuon events are responsible for an additional approximate to 25% contribution to the total mu(-)mu(-)mu(+) rate. The remaining 25% of events are likely to come from the internal bremsstrahlung of virtual photons into a muon pair.

Abstract: New results on inverse muon decay and coherent charged pion production by neutrinos are presented. The data come from the CHARM-II neutrino detector operated at the CERN wide-band neutrino beam. High-statistics data samples of 14500 inverse muon decay events and 3500 νμe elastic scattering events allow the determination of the electroweak parameters from the ratio of the cross-sections of neutral-to-charged-current neutrino electron scattering. The best fit values of the electroweak mixing angle sin 2 Ω w and the relative coupling strength ϱ of neutral and charged current are: sin 2 Ω w = 0.237 ± 0.014 and ϱ = 0.987 ± 0.042 . In the second topic, coherent single charged pion production was measured in neutrino and antineutrino beams. The measured cross-sections, averaged over the wide-band beam spectra and the glass target nuclei composition, are: σ(νμA → μ−π+A) = (51 ± 10) × 10−40 cm2 nucleus and σ( ν μ A → μ + π − A) = (43 ± 9) × 10 −40 cm 2 nucleus. The energy dependence shows the expected flattering of the cross-sections at high energy.

Abstract: We are reporting on a determination of neutral current coupling constants from a study of differential cross sections of muon-(anti)neutrino electron scattering. The results were obtained with the CHARM-II detector which was exposed to the CERN wide band neutrino beam in the years 1987 to 1991. A total of about 3000 ve and 3000 v e scattering events were observed. We present a preliminary value of sin2φw determined with the ratio of neutrino and antineutrino electron scattering cross-sections, based on the full data sample, and we give a determination of the effective vector and axial-vector neutral current coupling constants and the first measurement of the shape of the y-distributions based on 80% of the total statistics.

Abstract: We report on a measurement of coherent single charged pion production in neutrino-nucleus scattering. The analysis is based on data taken with the CHARM II detector in beams of muon-neutrinos and -antineutrinos. The event numbers amount to N(μ−π) = 748 and N(μ+π) = 631. Cross sections and their dependence on the neutrino energy are determined. The results are in agreement with the predictions of models based on the PCAC hypothesis.

Abstract: The neutrino detector CHARM-II at CERN, consisting of a large target calorimeter equipped with streamer tubes and a muon spectrometer, has been exposed to a test beam of electrons, pions and muons with momenta between 2 and 60 GeV/c in order to study the digital response of the streamer tubes, the analog response of the pickup strips and the momentum resolution of the muon spectrometer. Methods have been developed to carry the calibration results in space from the impact point of the test beam to the bulk of the detector and in time from the test beam period to all the data taking periods between 1987 and 1991, The number of hits along muon tracks was used to parametrize the dependence on fluctuations of temperature, tube voltage and gas composition. Curves and formulae are presented showing the energy response and the energy resolution for the different beam particles. The test beam data have been used to optimize and calibrate algorithms for the kinematical reconstruction of electron showers and for their extraction from the vast background of hadronic showers.

Abstract: A study of quasi-elastic production of charmed baryons in charged-current interactions of neutrinos with the nuclear emulsion target of CHORUS is presented. In a sample of about 46 000 interactions located in the emulsion, candidates for decays of short-lived particles were identified by using new automatic scanning systems and later confirmed through visual inspection. Criteria based both on the topological and kinematical characteristics of quasi-elastic charm production allowed a clear separation between events of this type and those in which charm is produced in deep inelastic processes. A final sample containing 13 candidates consistent with quasi-elastic production of a charmed baryon with an estimated background of 1.7 events was obtained. At the average neutrino energy of 27 GeV the cross-section for the total quasi-elastic production of charmed baryons relative to the νN charged-current cross-section was measured to be σ(QE)/σ(CC) = (0.23-0.06+0.02(stat)×10-2. Through an analysis of the topology at the production and decay vertices the relative cross-sections were measured separately for singly (Λc +, ∑c+, ∑c +*) and doubly (∑c++, ∑ c++*) charged baryons. © 2003 Published by Elsevier B.V., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract: We report on a search for associated charm production in neutrino charged-current interactions in the CHORUS experiment, based on the visual observation of charmed-particle decays. The search differs from those carried out so far in which the production of cc has been inferred from measurements of events with two or three muons in the final state, resulting from the decay of charmed hadrons. One event with a double charm-decay topology has been found and a corresponding background of 0.04 events has been evaluated. © 2002 Elsevier Science B.V. All rights reserved.

Abstract: During the years 1994-1997, the emulsion target of the CHORUS detector was exposed to the Wide Band Neutrino Beam from the CERN-SPS. About 170 000 neutrino interactions were successfully located in the emulsion. Improvements in the automatic emulsion scanning systems and application of different criteria allowed the sample of located events to be used for studies of charm production. We present a measurement of the production rate of D 0 mesons based on a sample of 25 693 located v μ charged-current (CC) interactions analysed so far. After reconstruction of the event topology in the vertex region, 283 D 0 decays were observed with an estimated background of 9.2 K 0 and Λ decays. The ratio of cross-section of D 0 production and v μ CC interactions is found to be (1.99 ± 0.13(stat.) ± 0.17(syst.)) × 10 -2 at 27 GeV average v μ energy. © 2002 Elsevier Science B. V.

Abstract: During the years 1994-1997, the emulsion target of the CHORUS detector was exposed to the CERN-SPS Wide Band Neutrino Beam. The improvements of the past few years in the automatic emulsion scanning systems allowed a sample of events located in emulsion to be used for studies of charm production. Based on a sample of 56172vμu charged-current interactions analysed so far, we find a value of Bμ = 0.093 ± 0.009(stat.) ± 0.009(syst.) for the semi-leptonic branching fraction of charm hadrons. The result for events with visible energy larger than 30 GeV, Bμ = 0.102 ± 0.016(stat.) ± 0.010(syst.), can be combined with the existing measurements of the dimuon rate to yield a value of 0.219 ± 0.022 for the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element \Vcd\. © 2002 Elsevier Science B.V.

Abstract: We are reporting an improved determination of the electroweak mixing angle sin2Θw from the ratio of νμe to ν μ e scattering cross sections. The CHARM II detector was exposed to neutrino and antineutrino wide band beams at the 450 GeV CERN SPS. Including new data collected in 1989 we have obtained 1316 ± 56 νμe and 1453 ± 62 ν μ e events. From the ratio of the visible cross sections we determined sin2Θ0=0.239 ± 0.009(stat) ± 0.007(syst) without radiative corrections and g V e g A e =0.047 ± 0.046 . Combining this last result with recent results on gAe at LEP we obtain gVe= −0.023 ± 0.023.

Abstract: A proton beam-dump experiment using the CHARM neutrino detector has been performed at the CERN SPS. We report the observation of events induced by prompt ν¯ μ neutrinos and confirm previous evidence for prompt electron neutrinos. The ratio of prompt (ν¯ e + ν e ) and (ν¯ μ +ν μ ) fluxes is found to be 0.48±0.12 (st atistical) ± 0.10 (systematic), whereas a flux ratio of 1 is expected for charmed meson production and subsequent semileptonic decay. The ν¯ μ to ν μ flux ratio obtained is 1.3 −0.6 +6 . We also observe 54 ± 19 (statistical) ± 9 (systematic) promp t muonless events, with shower energy in the range from 2 to 20 GeV, in excess of electron and muon neutrino interactions expected from D and D¯ meson decay.

These purely leptonic processes were studied using the CHARM calorimeter exposed to neutrino and antineutrino wide-band beams at the CERN super proton synchrotron. A total of 83±16 neutrino-electron and 112±21 antineutrino-electron events have been detected. From the measurement of the ratio of muon-neutrino and muon-antineutrino cross-sections a value of sin2 θ w =0.211±0.037 was obtained.

Abstract: The cross-section ratio of neutral-current and charged-current semileptonic interactions of muon-neutrinos on isoscalar nuclei has been measured with the result:Rv=0.3093±0.0031 for hadronic energy larger than 4 GeV. From this ratio we determined the electroweak mixing angle sin2θW, wheremc is the charm-quark mass in GeV/c2. Comparison with direct measurements ofmw andmz determines the radiative shift of the intermediate boson mass Δr=0.077±0.025(exp.)±0.038(syst.), in agreement with the prediction. Assuming the validity of the electroweak standard theory we determined ϱ=0.990−0.013(mc−1.5)±0.009(exp.)±0.003(theor.).

A ratio of the coupling constants g eνe g μνμ = 1.10 ± 0.05 at 〈Q 2 〉 ∽ 16 GeV 2 was derived in agreement with the universal coupling strength of the electron and muon families to the charged weak current.

Abstract: A search for heavy neutrinos was conducted in the neutrino beam produced by the 400 GeV proton beam-dump and in the 400 GeV wide-band neutrino beam at CERN. A heavy neutrino associated with the τ lepton was searched for in the beam-dump experiment. No assumption on the nature of heavy neutrinos was made in the wide-band beam experiment. A search was made for neutrinos decaying into two electrons and a light neutrino. Since no events were observed, an upper limit on the neutrino mixing angles as a function of the neutrino mass is derived. The beam-dump experiment is sensitive to a neutrino mass range of 10–250 MeV and an upper limit at 90% confidende level on the square of the neutrino mixing angle of θ10 −10 was obtained for neutrino masses greater than 180 MeV. The wide-band neutrino experiment is sensitive to neutrinos with a mass in a larger range (10–490 MeV), and for masses greater than 250 MeV yields an upper limit on the square of the neutrino mixing angle of θ10 −6 .

Abstract: A fast and effective algorithm for electromagnetic and hadronic shower separation has been developed for the digital sampling calorimeter of the CHARM II experiment. It is based on a generalization of the minimal spanning tree concept and can be easily applied to other existing calorimeters. In this particular application, which requires the highest efficiency for retaining electromagnetic showers, one gets, for 99% efficiency, a rejection factor of the order of 100 for hadronic showers.

Abstract: We report on experimental results obtained with the neutrino target calorimeter of the CHARM II detector. The experiment is being performed at CERN and its aim is to measure sin2θw, the electroweak mixing parameter, via the study of neutrino-electron scattering. The detector, installed on the SPS neutrino wide-band beam line, consists of a glass calorimeter instrumented with plastic streamer tubes and scintillation counters, and of a muon spectrometer. The performance of the calorimeter has been explored during a test run with electron and pion beams. Results concerning the detector response, the energy and angular resolution, and the e π separation are presented here.
