Charm Production and Fragmentation in Charged Current DIS
arXiv:hep-ph/9808464 · doi:10.1016/S0920-5632(99)00171-1
Abstract
In charged current deep inelastic scattering charm is dominantly produced in scattering events on strange quarks, thereby allowing for an experimental determination of the nucleon's strange sea density. A measurement of the energy spectrum of final state charm fragments (D-mesons) determines the charm fragmentation function at spacelike scales considerably below typical e^+e^- c.m.s. energies. NLO corrections to the naive s -> c parton model production picture are important and well understood.
