Özet

The CHORUS experiment is designed to search for nu(mu) --> nu(tau) oscillation with a hybrid detector system containing 800 kg nuclear emulsions as target and vertex detector. Run I (320 000 recorded nu(mu)CC in 1994/5) and more than half of the run II (460 000 nu(mu)CC in 1996/7) data taking have been successfully completed. Approximately 80 000 events have been analyzed so far, searching for tau(-) --> mu(-)<(nu)over bar>(mu)nu(tau) and tau(-) --> h(-)(n pi(0))nu(tau) decays. No candidate has been found, leading to a limit sin(2) 2 theta(mu tau) less than or equal to 4.5 10(-3) for large Delta m(2).
