Erratum: Next-to-leading order corrections to heavy flavor production in longitudinally polarized photon-nucleon collisions [Phys. Rev. D62, 114509 (2000)]

Next-to-leading order QCD corrections to one hadron-production in polarized pp collisions at RHIC

We calculate the next-to-leading order QCD corrections to the spin-dependent cross section for single-inclusive hadron production in hadronic collisions. This process will be soon studied experimentally at RHIC, providing a tool to unveil the polarized gluon distribution ∆g. We observe a considerably improvement in the perturbative stability for both unpolarized and polarized cross sections. Th...

Next-to-Leading-Order Corrections to the Production of Heavy-Flavour Jets in e+e− Collisions

In this paper we describe the calculation of the process e+e−→Z/γ→QQ+X, where Q is a heavy quark, at order αs. CERN-TH/97-219 April 14, 2008 On leave of absence from INFN, Milan, Italy

Photoproduction of Heavy Quarks in Next-to-Leading Order QCD with Longitudinally Polarized Initial States

We present all relevant details of our calculation of the complete next-to-leading order (O(α2 sα)) QCD corrections to heavy flavor photoproduction with longitudinally polarized point-like photons and hadrons. In particular we provide analytical results for the virtual plus soft gluon cross section. We carefully address the relevance of remaining theoretical uncertainties by varying, for instan...

Next-to-next-to-leading-order soft-gluon corrections in direct photon production

Abstract Previous work on soft-gluon resummation for direct photon production is extended to include additional subleading logarithmic terms through O(ααs) and some representative comparisons are made to experimental results from the E-706 and UA-6 Collaborations. The additional terms are small in magnitude, indicating good convergence properties to the level of accuracy calculated. The scale d...
