Measurement of neutrino-proton and antineutrino-proton elastic scattering

Measurements of the semileptonic weak-neutral-current reactions ..nu../sub ..mu../p..--> nu../sub ..mu../p and nu-bar/sub ..mu../p..-->..nu-bar/sub ..mu../p are presented. The experiment was performed using a 170-metric-ton high-resolution target detector in the BNL wide-band neutrino beam. Hi...

Zusammenfassung:	Measurements of the semileptonic weak-neutral-current reactions ..nu../sub ..mu../p..--> nu../sub ..mu../p and nu-bar/sub ..mu../p..-->..nu-bar/sub ..mu../p are presented. The experiment was performed using a 170-metric-ton high-resolution target detector in the BNL wide-band neutrino beam. High-statistics samples yield the absolute differential cross sections dsigma(..nu../sub ..mu../p)/dQ/sup 2/ and dsigma(nu-bar/sub ..mu../p)/dQ/sup 2/. A measurement of the axial-vector form factor G/sub A/(Q/sup 2/) is also presented. The results are in good agreement with the standard model SU(2) x U(1). The weak-neutral-current parameter sin/sup 2/theta/sub W/ is determined to be sin/sup 2/theta/sub W/ = 0.220 +- 0.016(stat)/sup +0.023//sub -0.031/(syst).
