The cross section ratio of neutral-current and charged-current semi-leptonic interactions of muon-neutrinos on isoscalar nuclei has been measured with the result: Rv=0.3093±0.0031 for hadronic energy larger than 4 GeV. From this ratio, the electroweak mixing angle is determined to be sin2θw=0.236+0.012(mc−1.5)±0.005 (exp.)±0.003 (theor.), where mc is the charm-quark mass in GeV/c2.

Abstract

The cross section ratio of neutral-current and charged-current semi-leptonic interactions of muon-neutrinos on isoscalar nuclei has been measured with the result: Rv=0.3093±0.0031 for hadronic energy larger than 4 GeV. From this ratio, the electroweak mixing angle is determined to be sin2θw=0.236+0.012(mc−1.5)±0.005 (exp.)±0.003 (theor.), where mc is the charm-quark mass in GeV/c2.
