Strange sea asymmetry from global QCD fits

Abstract

We present a preliminary account of a new global QCD analysis of DIS data, including recent $\nu ,\bar{\nu }$ DIS measurements. The model-independent cross section reanalysis by CCFR allows a new determination of the strange sea asymmetry, whose first moment is found to be small. The impact on the NuTeV measurement of ${\sin }^2{\theta }_W$ is discussed.
