Mass Corrections and Neutrino DIS

Abstract

Including the effects of the $\mathcal{O}(\gtrsim 1\mathrm{GeV})$ masses of the charm quark, $\tau$ lepton and target nucleon in DIS phenomenology is discussed with applications to CC neutrino DIS: Neutrino data for $F_2$ are revisited within the global analysis framework. A fully differential calculation refines the CC charm production process as a gate to extract $\{s(x),\bar{s}(x)\}$. New results are presented for a "heavy quark" version of the CTEQ6 set of PDFs and for (${\nu }_{\mu }\to {\nu }_{\tau }$ oscillation-signal) $\tau$ neutrino cross sections.
