An upper limit to the cross section for the reaction nu /sub mu /e/sup -/ to nu /sub mu /e/sup -/ at SPS energies

Candidates for the purely leptonic process nu /sub mu /e/sup -/ to nu /sub mu /e/sup -/ have been searched for in the bubble chamber Gargamelle exposed to the CERN-SPS antineutrino wide-band beam. No single e/sup -/, of energy greater than 1 GeV, was found in a total of 230000 pictures, correspondin...

description Candidates for the purely leptonic process nu /sub mu /e/sup -/ to nu /sub mu /e/sup -/ have been searched for in the bubble chamber Gargamelle exposed to the CERN-SPS antineutrino wide-band beam. No single e/sup -/, of energy greater than 1 GeV, was found in a total of 230000 pictures, corresponding to 7400 charged current events. This leads to an upper limit for the observed cross section of sigma /sub obs/<1.6*10/sup -42/(E/sub nu //GeV) cm/sup 2/ (90% C.L.). Interpretation of this value in terms of the standard Weinberg-Salam model yields an upper limit to the mixing parameter sin/sup 2/ theta /sub W/<0.39 at 90% C.L. (5 refs).
