Heavy 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 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...
متن کاملHeavy 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 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 کاملBeauty Quark Production in Deep Inelastic Scattering at Hera
The measurement of the beauty quark production cross section in deep inelastic scattering with the ZEUS detector at HERA is presented. The cross section for beauty quarks, measured in the kinematic range Q > 2 GeV and 0.05 < y < 0.7, and for events with at least one muon and one jet in the Breit frame, is somewhat above the next-to-leading order (NLO) QCD prediction, but in agreement within the...
