Phys. Rev. Lett. 72, 3452–3455 (1994)Precise measurement of the weak mixing angle in neutrino-nucleon scatteringReceived 10 March 1994; published in the issue dated 30 May 1994 We report a precise measurement of the weak mixing angle from the ratio of neutral current to charged current inclusive cross sections in deep-inelastic neutrino-nucleon scattering. The data were gathered at the CCFR neutrino detector in the Fermilab quadrupole-triplet beam, with neutrino energies up to 600 GeV. Using the on-shell definition, sin2θW==1-MW2/MZ2, we obtain sin2θW=0.2218±0.0025(stat)±0.0036(expt syst)±0.0037(model). © 1994 The American Physical Society URL:
