Heavy Quark Fragmentation in Deep Inelastic Scattering
We perform an analysis of semi-inclusive production of charm (D-mesons) in neutral current (NC) and charged current (CC) deep inelastic scattering (DIS) at full O(α s). Our calculation is based on the heavy quark scheme developed by Aivazis, Collins, Olness and Tung (ACOT) where we include anO(α s) calculation of quark scattering contributions for general masses and couplings. We review the rel...
متن کاملHeavy Quark Production in Deep-Inelastic Scattering
We review recent results from the H1 and ZEUS experiments at HERA on charm and beauty production in ep collisions at 300 318 GeV centre-of-mass energy.
متن کاملHeavy-quark correlations in deep inelastic scattering
Order αs QCD corrections to structure functions containing heavy quarks and to single heavy quark inclusive distributions in deep-inelastic electroproduction ( i . e. , γ∗(q)+P (p)→ Q(p1)+ X where X stands for any final hadronic state allowed by quantum-number conservation and P (p) is a proton of momentum p ) were recently published in [1] and [2], respectively. By combining the next-to-leadin...
متن کاملPolarised Quark Distributions from Deep Inelastic Scattering
Polarised quark distributions are extracted from semi-inclusive deep inelastic scattering data, which include the additional detection of a leading hadron to providestatisticaìàvour-tagging'. Results are combined from both proton and`neutron' targets to isolate the contributions to the nucleon spin of the individual quark avours, including the sea quarks. Spin asymmetries in the semi-inclusive ...
متن کاملHeavy Quark Production in Deep-Inelastic Scattering at HERA
Charm quarks produced in deep-inelastic scattering have been identified in sizable numbers by the H1 and ZEUS collaborations at HERA [1], and considerably more charm (and bottom) data are anticipated. At the theoretical level the reaction has already been studied extensively. In the framework where the heavy quark is not treated as a parton, leading order (LO) [2] and next-to-leading order (NLO...
