Measurement of muon-neutrino and -antineutrino scattering off electrons

Muon-neutrino and -antineutrino scattering off electrons was detected in a 19-ton Al spark chamber, exposed to the wide-band nu ( nu ) beam from the CERN proton synchrotron. The background was determined experimentally. 11 (10) genuine nu /sub mu -/( nu /sub mu -/) e scattering events were found. Th...

Descripción
Sumario:Muon-neutrino and -antineutrino scattering off electrons was detected in a 19-ton Al spark chamber, exposed to the wide-band nu ( nu ) beam from the CERN proton synchrotron. The background was determined experimentally. 11 (10) genuine nu /sub mu -/( nu /sub mu -/) e scattering events were found. The respective cross sections are (1.1+or-0.6)*10/sup -42/ (E/sub nu //GeV) cm/sup 2/ and (2.2+or-1.0) *10/sup -42/ (E/sub nu //GeV) cm/sup 2/. The analysis excludes a pure V-A interaction, and makes a pure V or A theory improbable. The data agree well with the Salam-Weinberg model and sin/sup 2/ theta /sub w /=0.35+or-0.08. (13 refs).
