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.

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 first analysis of the complete set of data collected by CHORUS in the years 1994-1997 is presented. The search for $\nut$ charged current events has been performed for both leptonic and hadronic decays of the $\tauu$ lepton. No $\tauu$ candidate has been found. A $\numtonut$ mixing is excluded down to $\sin2t$ = $6.8 \times 10^{-4}$ for large $\dm2$ (90\%~C.L.).

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.

Abstract

CHORUS is an experiment searching for $\numtonut$ oscillation in the CERN wide band neutrino beam with a {\sl 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 $\mu \bar{\nu}_\mu\nu_\tau$. In a sample of 31,423 $\num$ charged current interactions, no $\nu_\tau$ candidates were found. For large $\dm2$ values, a limit on the mixing angle of $\sin2t < 3.5 \times 10^{-3}$ at $90\%$ C.L. can be set, thus improving the previous best result.

Abstract

A new experimental apparatus, designed principally for a high sensitivity search for $\nu_{\mu}~\rightarrow~\nu_{\tau}$ 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.
