Electroproduction of Heavy Quarks at Nlo
نویسنده
چکیده
Heavy quark production in deeply inelastic electron proton scattering (DIS) has long been recognized as a candidate process for extracting the gluon distribution in the proton because the process is almost exclusively dominated by photon-gluon fusion . The cross section for heavy quark production in DIS is given in terms of the heavy quark structure functions F2(x,Q ,m) and FL(x,Q ,m). A calculation of these in next-to-leading order (NLO) QCD has been available for several years . However, only recently have they been calculated in a fully differential form at NLO . The relation between the cross section and the structure functions, in terms of the usual DIS kinematic variables x, y and Q, is as follows:

Sudakov Resummation for Electroproduction of Heavy Quarks
The leading and next-to-leading threshold logarithms of the QCD corrections to electroproduction of heavy quarks in single-particle inclusive kinematics are resummed to all orders in perturbation theory. The resummed cross-section is used to derive the NLO and NNLO results near threshold and their numerical impact on the charm structure function is studied. Talk at the ‘6th International Worksh...

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 کاملOn the role of heavy flavor parton distributions at high energy colliders
We compare ‘fixed flavor number scheme’ (FFNS) and ‘variable flavor number scheme’ (VFNS) parton model predictions at high energy colliders. Based on our recent LO– and NLO–FFNS dynamical parton distributions, we generate radiatively two sets of VFNS parton distributions where also the heavy quark flavors h = c, b, t are considered as massless partons within the nucleon. By studying the role of...

Heavy quarks are copiously produced in two-photon collisions at ee colliders. The theoretical predictions including QCD radiative corrections are compared to recent experimental data on γγ production of charm quarks at PETRA, PEP, TRISTAN and LEP. Photoproduction of heavy quarks at HERA is an important tool to measure the gluon distribution in the proton. New theoretical results on heavy quark ...
متن کاملHard Exclusive Production of a Vector Meson
The processes of a light neutral vector meson, V = ρ 0 , ω, φ, electroproduction and a heavy quarkonium, V = J/Ψ, Υ, photoproduction are studied in the framework of QCD factorization. We derive a complete set of hard-scattering amplitudes which describe these processes at next-to-leading order (NLO).
