The CHORUS experiment to search for $\nu_{\mu} \rightarrow \nu_{\tau}$ oscillation / CHORUS Collaboration
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 CHORUS neutrino oscillation search experiment / CHORUS Collaboration
The CHORUS experiment has successfully finished run I (320~000 recorded \numu\ CC in 94/95) and performed half of run II (225~000 \numu\ CC in 96). The analysis chain was exercised on a small data sample for the muonic \tdecay\ search using for the first time fully automatic emulsion scanning. [...]

A Search for $\nu_\mu \to \nu_\tau$ Oscillation / CHORUS Collaboration
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. [...]

Search for $\nu_\mu \to \nu_\tau$ oscillation using the $\tau$ decay modes into a single charged particle / CHORUS Collaboration
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. [...]

Observation of neutrino induced diffractive $D_s^{*+}$ production and subsequent decay $D_s^{*+} \to D_s^+ \to \tau^+ \to \mu^+$ / CHORUS Collaboration
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 $\tau^+\rightarrow \mu^+\nu_\mu\bar{\nu_\tau}$.

New results from a search for $\nu_{\mu} \to \nu_{\tau}$ and $\nu_{e} \to \nu_{\tau}$ oscillation / CHORUS Collaboration
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. [...]

Observation of weak neutral current neutrino production of $J/\psi$ / CHORUS Collaboration
Observation of \jpsi production by neutrinos in the calorimeter of the CHORUS detector exposed to the CERN SPS wide-band \numu beam is reported. A spectrum-averaged cross-section $\sigma^{\mathrm{J/\psi}}$ = (6.3 $\pm$ 3.0) $\times \mathrm{10^{-41}~cm^{2}}$ is obtained for 20 GeV $\leq E_{\nu} \leq$ 200 GeV. [...]

Nuclear emulsions in a large, hybrid experiment (CHORUS) to search for $\nu_{\mu} \to \nu_{\tau}$ oscillations / Aoki, S ; Barbuto, E ; Bozza, C ; Fabre, Jean-Paul ; Flegel, Wilfried ; Grella, G ; Güler, M ; Hara, T ; Hoshino, K ; Ishii, Y et al.
We describe the (2*800 kg) emulsion target in the CHORUS hybrid detector set-up for the search of nu /sub mu / to nu /sub tau / oscillations, together with the CERN pouring and processing facilities (upgraded for this purpose), and the techniques employed to treat the emulsions used as the active target in the experiment.
