The ratio R of muon neutrino-electron and antineutrino-electron cross sections has been determined based on a sample of 46 ± 12 neutrino events and 77 ± 19 antineutrino events obtained in the CHARM fine-grain calorimeter using the CERN Super Proton Synchroton horn-focused wide-band beams. The experimental result is R=1.37−0.44+0.65, corresponding to a value of sin2θW=0.215±0.040. The systematic error of sin2θW is estimated to be ±0.015.

Abstract

The ratio R of muon neutrino-electron and antineutrino-electron cross sections has been determined based on a sample of 46 ± 12 neutrino events and 77 ± 19 antineutrino events obtained in the CHARM fine-grain calorimeter using the CERN Super Proton Synchroton horn-focused wide-band beams. The experimental result is R=1.37−0.44+0.65, corresponding to a value of sin2θW=0.215±0.040. The systematic error of sin2θW is estimated to be ±0.015.
