2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/43566We present a preliminary account of a new global QCD analysis of DIS data, including recent $ν, \bar ν$ 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 $\sin^2 θ_W$ is discussed.Presentation at the DIS 2003 conferenceHigh Energy Physics - Phenomenologytext
