We report the results of a study of electroweak parameters from observations of neutral-current $$\nu$$N deeply inelastic scattering in the CCFR detector at the FNAL Tevatron Quadrupole Triplet neutrino beam. An improved extraction of the weak mixing angle in the on-shell renormalization scheme, incorporating additional data and with an improved technique for constraining systematic errors, is presented. Within the Standard Model, this result constrains the W mass with a precision comparable to that from direct measurements. The result is also presented in a model-independent form, as constraints on neutral-current quark-neutrino couplings, to facilitate comparisons with theories outside the Standard Model. Using this result, limits on new four-fermion interactions, leptoquarks and neutrino oscillations are presented. Prospects for a successor experiment, NuTeV (FNAL-E815), are also presented.
