Measurement of the neutral to charged current cross section ratios for νsub(μ)-interactions on proton and neutron

Creators

Description

In an exposure of the bubble chamber BEBC, filled with deuterium, to the CERN SPS wideband neutrino beam the neutral to charged current cross-section ratios on proton, neutron and deuteriuum has been measured. The values found are: Rsup(P)=0.478+-0.033 (stat) +-0.030 (syst); Rsup(n)=0.262+-0.017 (stat)N+-0.020 (syst); Rsup(N)=0.335+-0.016 (stat)+-0.020 (syst). The resulting values for the neutral current chiral coupling constants are: usub(L)sup(2)=0.14+-0.04 and dsub(L)sup(2)=0.18+-0.05. In the Weinberg-Salam model this corresponds to sinsup(2)THETAsub(w)=0.21+-0.03. (author)
