Results from Gargamelle neutrino experiment at CERN SPS

Three results are presented: a) from the study of 117 neutrino induced dimuons events a production rate of sigma(μ+μ-)/sigma(μ-) = (0.72 +- 0.14) x 10-2 has been measured. The μ+μ- channel is found to be dominated by D-meson production and decay. b) The inverse muon decay reaction is observed for the first time with a clear signal of 26 +- 6 events in good agreement with predictions from standard V-A theory. c) Results with the complete statistics are presented for the pure leptonic neutral current reaction (νsub(μ)e- → νsub(μ)e-). The measured cross section is now in agreement with other experiments and with the predictions from the standard SU(2) x U(1) model. (orig.)
