Soft gluon resummation for heavy quark production in charged current deep inelastic scattering

Abstract We study soft-gluon radiation for heavy quark production in charged-current Deep Inelastic Scattering processes. We resum large- x contributions to the MS coefficient function to next-to-leading logarithmic accuracy and present results for charm quark structure functions for several values of the ratio m c / Q . The effect of soft resummation turns out to be visible, especially at small Q 2 , and the results exhibit very little dependence on factorization and renormalization scales. The impact of our calculation on structure function measurements at NuTeV and HERA experiments is discussed.
