Abstract
The cross section ratios of neutral and charged current interactions induced by neutrinos and antineutrinos in iron have been measured in the 200 GeV narrow-band beam at the CERN SPS. We find Rv=0.301±0.007 and Rv=0.363±0.015 for a hadron energy cut of 10 GeV. The results are in agreement with the standard model of electroweak interactions. In the {Mathematical expression} renormalization scheme at the scale of the W boson mass {Mathematical expression} is obtained, where the error represents the experimental uncertainty. The theoretical uncertainty is estimated to be Δsin2θW=±0.006.
