Elastic scattering of neutrino on proton is studied in the Weinberg-Salam gauge model of neutral currents. Particular attention is paid to the experimental cuts relevant to two recent BNL experiments and spectra averaging so that model predictions can be directly compared to the experimental data. The uncertainty in the calculation due to changes in the parameters which are not well determined such as the mass of the axial vector meson is emphasized. It is concluded that the simple Weinberg-Salam gauge model with sin/sup 2/ theta/sub W/ approximately 0.4 is consistent with the recent measurement of R/sub el/sup nu/ = less than sigma( (nu + p ..-->.. nu + p) greater than/less than sigma(nu + n ..-->.. ..mu../sup -/ + p) greater than provided M/sub A/ approximately 1.15 GeV which is within the range of uncertainty of this parameter. Similar calculation for the case of antineutrino proton elastic scattering, i.e., R/sub el/sub 3//sup anti nu/ = less than sigma (anti nu + p ..-->.. anti nu + p) greater than/less than sigma (anti nu + p ..-->.. ..mu../sup +/ + n) greater than is presented.
