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...
متن کاملNext-to-next-to-leading order soft-gluon corrections in top quark hadroproduction
We calculate next-to-next-to-leading order soft-gluon corrections to top quark total and differential cross sections in hadron colliders. We increase the accuracy of our previous estimates by including additional subleading terms, including next-to-next-to-next-toleading-logarithmic and some virtual terms. We show that the kinematics dependence of the cross section vanishes near threshold and i...
متن کاملSupersymmetric next-to-next-to-leading order corrections to Higgs boson production in gluon fusion
We compute the total cross section for the production of a light CP even Higgs boson within the framework of supersymmetric QCD up to next-to-next-to-leading order. Technical subtleties in connection to the evaluation of three-loop Feynman integrals with many mass scales are discussed in detail and explicit results for the counterterms of the evanescent couplings are provided. The new results a...
متن کاملNext-to-Next-to-Next-to-Leading-Order Soft-Gluon Corrections in Hard-Scattering Processes Near Threshold
I present a unified calculation of soft-gluon corrections to hard-scattering cross sections through next-to-next-to-next-to-leading order (NNNLO). Master formulas are derived, from a threshold resummation formalism, that can be applied to total and differential cross sections for hard-scattering processes in hadron colliders. I also present numerical results for charged Higgs production at the ...
متن کاملNext-to-Next-to-Leading-Order Collinear and Soft Gluon Corrections for T-Channel Single Top Quark Production
I present the resummation of collinear and soft gluon corrections to single top quark production in the t channel at next-to-next-to-leading logarithm (NNLL) accuracy using two-loop soft anomalous dimensions. The expansion of the resummed cross section yields approximate next-to-next-to-leading order (NNLO) cross sections. Numerical results for t-channel single top quark (or single antitop) pro...
