TL;DR
This paper presents a new global QCD analysis incorporating recent neutrino DIS data, leading to a refined understanding of strange sea asymmetry and its implications for electroweak measurements.
Contribution
It introduces a model-independent reanalysis of DIS data that provides a novel determination of strange sea asymmetry and discusses its impact on the NuTeV measurement of .
Findings
Strange sea asymmetry's first moment is small.
Reanalysis impacts measurement in NuTeV.
Incorporates recent neutrino DIS data.
Abstract
We present a preliminary account of a new global QCD analysis of DIS data, including recent 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 is discussed.
