Abstract We present an analysis of the neutrino event sample recorded in the Frejus experiment. This sample which corresponds to the 1.56 kt yr final sensitivity of the experiment is compared to the predictions of a Monte Carlo neutrino simulation program. It is based on a recent calculation of the atmospheric neutrino flux at the Frejus latitude which takes into account muon polarization effects. The comparison is performed on the distributions of the visible energy, the zenith angle and the neutrino flavor. Good agreement is obtained between the data and the simulation within statistics.

Abstract With the Frejus 900 ton calorimeter (550 ton fiducial), a search for nucleon decay events into anti-neutrino plus meson has been performed. No signal is found for a sensitivity of 1.3 kiloton × year. Lower lifetime limits for various decay modes range from 0.9 to 2.9 10 31 years (at 90% C.L.).

Lower limits on the nucleon lifetime in channels containing at least one positron or muon are given. The analysis is based on 4 years of data taking with the Fréjus detector. Various approaches to determine the background from atmospheric neutrinos are discussed and two different nuclear models are used in event simulations. The limits obtained range from 1031 years forp→e+K*0 to 1.5·1032 years forp→e+K*0 to 1.5·1032 years forp→µ+γ.
