Description

We describe a high statistics measurement from deep inelastic neutrino-nucleon scattering of the electroweak parameters rho and sin2THETAsub(W), performed in the Fermilab narrow-band neutrino beam. Our measurement uses a radius-dependent cut in y=Esub(H)/Esub(ν) which reduces the systematic error in sin2THETAsub(W), and incorporates electromagnetic and electroweak radiative corrections. In a renormalization scheme where sin2THETAsub(W) identical 1 - msub(W)2/msup(Z2), a value of sin2THETAsub(W) = 0.242 +- 0.011 +- 0.005 is obtained fixing rho = 1. If both sin2THETAsub(W) and rho are allowed to vary in a fit to our data, we measure rho = 0.991 +- 0.025 +- 0.009. (orig.)
