Abstract: A new experimental apparatus, designed principally for a high sensitivity search for nu( --> mu(tau) oscillation, has been successfully constructed and made operational by the CHORUS Collaboration for the CERN-WA95 experiment. It consists of a large emulsion target, a scintillating fiber tracker system with optoelectronics read-out, an air-core magnet, a set of trigger hodoscopes, a calorimeter based on the lead/scintillating-fiber technique, and a muon spectrometer. The design, construction and performance of the entire apparatus and of the different detectors are described.

Abstract: 23 páginas, 26 figuras, 5 tablas.-- PACS nrs.: 95.55.Vj; 28.85.+c; 07.75.+h; 07.05.Kf; 14.40.Aq.-- et al., The particle identification (PID) methods used for the calculation of secondary pion yields with the HARP forward spectrometer are presented. Information from time of flight and Cherenkov detectors is combined using likelihood techniques. The efficiencies and purities associated with the different PID selection criteria are obtained from the data. For the proton-aluminium interactions at 12.9 GeV/c incident momentum, the PID efficiencies for positive pions are 86% in the momentum range below 2 GeV/c, 92% between 2 and 3 GeV/c and 98% in the momentum range above 3 GeV/c. The purity of the selection is better than 92% for all momenta. Special emphasis has been put on understanding the main error sources. The final PID uncertainty on the pion yield is 3.3%., We gratefully acknowledge the help and support of the PS beam staff and of the numerous technical collaborators who contributed to the detector design, construction, commissioning, and operation. The experiment was made possible by grants from the Institut Interuniversitaire des Sciences Nucléaires (Belgium), Ministerio de Educación y Ciencia, Grant FPA2003-06921-c02-02 and Generalitat Valenciana, grant GV00-054-1, CERN (Geneva, Switzerland), the German Bundesministerium für Bildung und Forschung (Germany), the Istituto Nazionale di Fisica Nucleare (Italy), INR RAS (Moscow), and the Particle Physics and Astronomy Research Council (UK).

Abstract: HARP is a high-statistics, large solid angle experiment to measure hadron production using proton and pion beams with momenta between 1.5 and 15 GeV/c impinging on many different solid and liquid targets from low to high Z. The experiment, located in the T9 beam of the CERN PS, took data in 2001 and 2002. For the measurement of momenta of produced particles and for the identification of particle types, the experiment includes a large-angle spectrometer, based on a Time Projection Chamber and a system of Resistive Plate Chambers, and a forward spectrometer equipped with a set of large drift chambers, a threshold Cherenkov detector, a time-of-flight wall and an electromagnetic calorimeter. The large angle system uses a solenoidal magnet, while the forward spectrometer is based on a dipole magnet. Redundancy in particle identification has been sought, to enable the cross-calibration of efficiencies and to obtain a few percent overall accuracy in the cross-section measurements. Detector construction, operation and initial physics performances are reported. In addition, the full chain for data recording and analysis, from trigger to the software framework, is described.

Abstract: We built and tested on charged particle beams the high energy-resolution calorimeter for the CHORUS experiment, which searches for νμ-ντ oscillations in the CERN Wide Band Neutrino Beam. This calorimeter is longitudinally divided into three sectors: one electromagnetic and two hadronic. The first two upstream sectors are made of lead and plastic scintillating fibers in the volume ratio of 4 1 , and they represent the first large scale application of this technique for combined electromagnetic and hadronic calorimetry. The third sector is made of a sandwich of lead plates and scintillator strips and complements the measurement of the hadronic energy flow. In this paper, we briefly describe the calorimeter design and we show results on its response to electrons and pions, obtained from tests performed at the CERN SPS and PS. An energy resolution of σ(E)/E=(32.3±2.4)%/ E(GeV) + (1.4±0.7)% was achieved for pions, and σ(E)/E=(13.8±0.9)%/ E(GeV) + (−0.2±0.4)% for electrons.

Abstract: In the framework of the CHORUS experiment for the search of v μ ↔ v τ oscillations at CERN, we have built the high resolution calorimeter, intended for the measurement of the energy of hadronic showers produced in neutrino interactions. The calorimeter consists of three parts. The first two are made of lead and plastic scintillating fibers in the volume ratio 4 : 1, such as to achieve compensation. The third is a sandwich of lead plates and scintillator strips in the same volume ratio. The techniques used for the construction of the calorimeter are described, as well as its performance in shower and muon detection. We used electron, pion and muon beams in the energy range 2–100 GeV for this purpose.

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}.

Aim of the calorimeter is to measure the energy and direction of hadronic showers produced in interactions of the neutrinos in a nuclear emulsion target and to track through-going muons. It is a longitudinally segmented sampling device made of lead and scintillating fibers or strips. This detector has been exposed to beams of pions and electrons of defined momentum for calibration. The method used for energy calibration and results on the calorimeter performance are reported.

Abstract: This document presents the physics case for bringing SciBar, the fully active, finely segmented tracking detector at KEK, to the FNAL Booster Neutrino Beam (BNB) line. This unique opportunity arose with the termination of K2K beam operations in 2005. At that time, the SciBar detector became available for use in other neutrino beam lines, including the BNB, which has been providing neutrinos to the MiniBooNE experiment since late 2002. The physics that can be done with SciBar/BNB can be put into three categories, each involving several measurements. First are neutrino cross section measurements which are interesting in their own right, including analyses of multi-particle final states, with unprecedented statistics. Second are measurements of processes that represent the signal and primary background channels for the upcoming T2K experiment. Third are measurements which improve existing or planned MiniBooNE analyses and the understanding of the BNB, both in neutrino and antineutrino mode. For each of these proposed measurements, the SciBar/BNB combination presents a unique opportunity or will significantly improve upon current or near-future experiments for several reasons. First, the fine granularity of SciBar allows detailed reconstruction of final states not possible with the MiniBooNE detector. Additionally, the BNB neutrino energy spectrum is amore » close match to the expected T2K energy spectrum in a region where cross sections are expected to vary dramatically with energy. As a result, the SciBar/BNB combination will provide cross-section measurements in an energy range complementary to MINERvA and complete the knowledge of neutrino cross sections over the entire energy range of interest to the upcoming off-axis experiments.« less

Abstract: A new near detector for the K2K long baseline neutrino experiment, the SciBar, was constructed and started data taking to study neutrino interactions. In K2K, neutrino oscillation is studied by comparing the number of neutrino interactions and energy spectrum between near and far detectors. In order to study neutrino oscillations more precisely, it is necessary to improve the measurement of neutrino spectrum and interactions below 1 GeV, where the latest K2K results suggest maximum oscillation. For that purpose, SciBar is designed to be fully active with fine segmentation. We present the design and basic performance. All detector components have been working as expected. Also presented are the measurements of charged current interactions which are used in the latest K2K oscillation analysis

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: The construction of modules and the assembly of the calorimeter for CHORUS, an experiment that searches for nu(mu) nu(tau) oscillation, have been completed. Within the experiment, the calorimeter is required to measure the energy of hadronic showers produced in neutrino interactions with a resolution of similar to 30%/root E(GeV). To achieve this performance, the technique, developed in recent years, of embedding scintillating fibers of 1 mm diameter into a lead matrix has been adopted for the most upstream part of the calorimeter. A more conventional system, of alternating layers of lead and scintillator strips, was used for the rest. Details of module construction as well as results obtained when modules were exposed to electron and muon beams are presented.

Abstract: The CHORUS Collaboration is presently building a new detector for the search of ν μ - ν τ oscillations in the CERN neutrino beam, the experiment being sensitive to a mixing angle an order of magnitude smaller than the present limit. The basic components of the CHORUS “hybrid” detector are an active target made of nuclear emulsions, an air core spectrometer with scintillating fiber tracking, a high resolution calorimeter and a muon spectrometer. An account is given here of the design of the 110-tons compensating calorimeter, made of 1 mm diameter scintillating fibers embedded in a lead matrix, and of the test results from the first modules produced.

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: We present results for muon neutrino oscillation in the KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment. K2K uses an accelerator-produced muon neutrino beam with a mean energy of 1.3 GeV directed at the Super-Kamiokande detector. We observed the energy dependent disappearance of muon neutrino, which we presume have oscillated to tau neutrino. The probability that we would observe these results if there is no neutrino oscillation is 0.0050% (4.0 sigma)., Comment: 5 pages, 4 figures

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: We report on a study of the differential cross section dσ/dy for the processes of elastic νμ- and ν μ - electron scattering. The data on which this analysis is based were recorded between 1987 and 1990 with the CHARM II detector in the wide band neutrino beam at the CERN-SPS. For the first time the shapes of these y-distributions have been determined in a model-independent way. A fit to the data yields for the squares of the neutral coupling constants the ratio gR2/gL2=0.60 ± 0.19 (stat.) ± 0.09 (syst.).

The results were obtained with the CHARM-II detector which was exposed to the CERN wide band neutrino beam in the years 1987–1990. A total of about 2100 ve and 2200 ve scattering events were observed. From a comparison between the data and predicted event distributions, the effective vector and axial-vector neutral current coupling constants of the electron were determined to be g e v =−0.025±0.019 and g e A =−0.503±0.018.

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: The weak nucleon axial-vector form factor for quasielastic interactions is determined using neutrino interaction data from the K2K Scintillating Fiber detector in the neutrino beam at KEK. More than 12 000 events are analyzed, of which half are charged-current quasielastic interactions ${\ensuremath{\nu}}_{\ensuremath{\mu}}n\ensuremath{\rightarrow}{\ensuremath{\mu}}^{\ensuremath{-}}p$ occurring primarily in oxygen nuclei. We use a relativistic Fermi gas model for oxygen and assume the form factor is approximately a dipole with one parameter, the axial-vector mass ${M}_{A}$, and fit to the shape of the distribution of the square of the momentum transfer from the nucleon to the nucleus. Our best fit result for ${M}_{A}=1.20\ifmmode\pm\else\textpm\fi{}0.12\text{ }\text{ }\mathrm{GeV}$. Furthermore, this analysis includes updated vector form factors from recent electron scattering experiments and a discussion of the effects of the nucleon momentum on the shape of the fitted distributions.

Abstract: New measurements of the total crosssections of charged-current interactions of muonneutrinos and antineutrinos on isoscalar nuclei have been performed. Data were recorded in an exposure of the CHARM detector in an 160 GeV narrow-band beam. The antineutrino flux was determined from the measurements of the pion and kaon flux, and independently from the muon flux measured in the shield; the two methods are found to agree. The neutrino flux was determined from the muon flux ratio forv μ and $$\bar v_\mu $$ runs which was normalized to the antineutrino flux. The cross-section slopes thus determined are $$\begin{gathered} \sigma _T^{\bar v} /E = (0.335 \pm 0.004(stat) \hfill \\ \pm 0.010(syst)).10^{ - 38} cm^2 /(GeV \cdot nucleon) \hfill \\ \sigma _T^v /E = (0.686 \pm 0.002(stat) \hfill \\ \pm 0.020(syst)).10^{ - 38} cm^2 /(GeV \cdot nucleon) \hfill \\ \end{gathered} $$ The momentum sum of the quarks in the nucleon and the ratio of sea quark to total quark momentum are derived from the measurements.

Abstract: The CHARM II Collaboration is building a massive, fine-grained and low-density detector for the study of neutrino-electron scattering. Its target calorimeter consists of 441 detector planes with 155 232 plastic streamer tubes with digital readout of the wires and analog readout of external pickup strips. At the time of this report, about 25% of the calorimeter planes were equipped with electronics. Results on the performance of these tubes are presented as obtained with cosmic-rays and with electron and pion beams. We have also investigated the use of water vapour as an additive to the gas to suppress coating of the anode wires. The use of water would be of particular importance when using the tubes in a high-rate environment.

Abstract: Differential cross sections dσ/dy have been measured in semileptonic neutral- and charged-current reactions induced by neutrinos and antineutrinos. The comparison of the neutral- and the charged-current differential cross sections allows the direct determination of the chiral coupling of the neutral ( v v ) current to left- and right-handed quarks. The result, with a value of gR2 = 0.042±0.010, is the first direct determination, with a significance of more than four standard deviations, of a non-zero value of gR.

Abstract: A moments analysis of the Λp system produced forwards (t< 1 GeV2) by 8.25 GeV/c K− mesons in the reaction K−p → Λpp has been performed. Significant structure is observed in the double moments H(LMlm) describing the decay of the Λp system and the subsequent Λ decay for L ⩽ 4. This structure can be interpreted in terms of the production of a resonance of spin-parity JP = 2−, with a mass and width of 2235±50 MeV and ∼ 200 MeV, respectively. The production cross section for the Λp decay mode is ∼ 1.5 μb.

Abstract: The ratio R of muon neutrino-electron and antineutrino-electron cross sections has been determined based on a sample of 46 ± 12 neutrino events and 77 ± 19 antineutrino events obtained in the CHARM fine-grain calorimeter using the CERN Super Proton Synchroton horn-focused wide-band beams. The experimental result is R=1.37−0.44+0.65, corresponding to a value of sin2θW=0.215±0.040. The systematic error of sin2θW is estimated to be ±0.015.

Abstract: We present results for the hypercharge exchange reaction K−p→f' λ from a high statistics experiment at 8.25 GeV/c using the CERN 2m HBC. The total and differential cross sections have been measured; the polarisation of the Λ hyperon and the f' density matrix elements have been calculated as functions of momentum transfer. We also present detailed information on the relative strength of the natural and unnatural parity exchange contributions to the production mechanism.

Abstract: Inclusive Ξ− production is studied in K−p interactions at 8.25 GeV/c using about 8000 events. An analysis based on the triple-Regge model shows that the Λα − Λγ and Σβ − Σδ exchanges explain the forward Ξ− production. Ξ(1530) properties are also studied and are found to be similar to those of Ξ−'s. Finally, a study of the production of Ω− based on 67 events shows that Ω's are also produced by hyperon exchange.

Abstract: The production ofK* resonances has been studied in the reaction$K^ - p \to \bar K^0 \pi ^ - p$ at 8.25 GeV/c. The data comes from a high statistics bubble chamber experiment (180 events/μb). Masses, widths and production cross-sections have been determined for the first threeK*'s. The contributions from natural and unnatural parity exchange have been obtained for theK*(890) and theK*(1420). A partial wave analysis of theK π system from threshold to 1.9 GeV provides evidence for a 0+ enhancement near 1.4 GeV which could be interpreted as the κ(1350).

Abstract: Using the reaction K−p → Λ + X at 8.25 GeV/c we compare off-shell KK and pp interactions to on-shell pp interactions. The charged multiplicities are studied as functions of the off-shell c.m.s. energy √ s = Mx. Agreement is found between on- and off-shell pp reactions. It is shown that the charged multiplicities in KK interactions are lower than in pp. A KNO scaling is observed as a function of Mx2. The universal curve fitted by Slattery reproduces our data. Distinction has also been made between total inelastic and annihilation reactions.
