The large area Emulsion Tracker of the CHORUS experiment (2001)

Aoki, S, Dupraz, J P, Fabre, Jean-Paul, Flegel, Wilfried, Hara, T, Ishii, Y, ...

A new type of tracking device using large area nuclear emulsion sheets was developed for the short baseline neutrino oscillation experiment, CERN-WA95/CHORUS. The emulsion tracker is made of three...

Atlas MDT Muon Chamber (2001)

Flegel, Wilfried

Semi-automatic tube assembly for BOL and BML prototypes

Observation of weak neutral current neutrino production of $J/\psi$ (2001)

Eskut, E, Kayis-Topaksu, A, Onengüt, G, Van Dantzig, R, De Jong, M, Konijn, J, ...

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...

New results from a search for $\nu_{\mu} \to \nu_{\tau}$ and $\nu_{e} \to \nu_{\tau}$ oscillation (2000)

Eskut, E, Kayis-Topaksu, A, Onengüt, G, Van Dantzig, R, De Jong, M, Konijn, J, ...

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...

Leading-order QCD Analysis of Neutrino-Induced Dimuon Events (1998)

Vilain, P, Wilquet, G, Beyer, R, Flegel, Wilfried, Mouthuy, T, Øverås, H, ...

The results of a leading-order QCD analysis of neutrino-induced charm production are presented. They are based on a sample of 4111 $\numu$- and 871 $\anumu$-induced opposite-sign dimuon events with...

Search for $\nu_\mu \to \nu_\tau$ oscillation using the $\tau$ decay modes into a single charged particle (1998)

Eskut, E, Kayis, A, Onengüt, G, Van Dantzig, R, De Jong, M, Konijn, J, ...

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...

Experimental search for muonic photons (1998)

Vilain, P, Wilquet, G, Beyer, R, Flegel, Wilfried, Mouthuy, T, Øverås, H, ...

We report new limits on the production of muonic photons in the CERN neutrino beam. The results are based on the analysis of neutrino production of dimuons in the CHARM II detector. A $90\%$ CL limit...

A Search for $\nu_\mu \to \nu_\tau$ Oscillation (1998)

Eskut, E, Kayis, A, Onengüt, G, Van Dantzig, R, De Jong, M, Konijn, J, ...

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....

Running experience with the hexagonal toroidal air-core magnet of the CHORUS neutrino detector (1997)

Bergsma, F, Cataneo, F, Flegel, Wilfried, Gerwig, H, Giudici, P A, Panman, J, ...

We report on the running experience with a special toroidal air-core magnet of hexagonal shape used in the magnetic spectrometer of the CHORUS experiment at CERN. The novel and unique features of...

The CHORUS scintillating fiber tracker and its monitoring systems (1997)

Annis, P, Aoki, S, Brooijmans, G, Brunner, J, Dupraz, J P, Dupont, J, ...

A scintillating fiber tracker system consisting of more than one million fibers has been successfully constructed and made operational for the CERN WA95/CHORUS experiment. The design and construction...
