Higher Mellin Moments for Charged Current DIS
We report on our recent results for deep-inelastic neutrino(ν)-proton(P) scattering. We have computed the perturbative QCD corrections to three loops for the charged current structure functions F2, FL and F3 for the combination νP− ν̄P. In leading twist approximation we have calculated the first six odd-integer Mellin moments in the case of F2 and FL and the first six even-integer moments in the...
متن کاملCharm Production and Fragmentation in Charged Current DIS
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 ee c.m.s. energies. NLO ...
متن کاملThe Charm{Strange Contribution to Charged{Current DIS Structure Functions
We review the present theoretical knowledge of the charm{strange contribution to charged{current DIS structure functions. In particular, the uncertainties arising from the choice of the factorization scale, of the massive QCD scheme, and of the parton t are discussed.
متن کامل2 Neutral and Charged Current Dis at Large Q
Data from the HERA collider experiments, H1 and ZEUS, have been fundamental to the rapid recent development of our understanding of the partonic composition of the proton and of QCD. This report focuses on inclusive measurements of neutral and charged current cross sections at HERA, using the full available data taken to date. The present precision on the proton parton densities and the further...
