Mass Corrections and Neutrino DIS

Abstract

Including the effects of the ${\cal{O}}(\gtrsim 1 {\rm GeV})$ masses of the charm quark, $τ$ 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 ($ν_μ \to ν_τ$ oscillation-signal) $τ$ neutrino cross sections.
