Soft-gluon resummation and NNLO corrections for direct photon production
The resummation of threshold logarithms for direct photon production cross sections in hadronic collisions is presented. The resummation is based on the factorization properties of the cross section and is formulated at next-to-leading logarithmic or higher accuracy. Full analytical and numerical results for the next-to-next-toleading order expansion of the resummed cross section are given. A s...
متن کاملNNLO corrections to charmless hadronic B decays
We report on the status of the perturbative calculation in the QCD factorization framework to charmless hadronic B meson decays and present a compilation of available NNLO results. * Speaker. † I would like to thank Volker Pilipp for a fruitful collaboration on part of the subjects presented in this article and the organizers of EFT09 for creating a pleasant and stimulating workshop atmosphere.
متن کاملOn the NNLO QCD corrections to single-top production at the LHC
We present a fully-differential calculation of the NNLO QCD corrections to the t-channel mechanism for producing single top quarks at the LHC. We work in the structure function approximation, computing QCD corrections to the lightand heavy-quark lines separately and neglecting the dynamical cross-talk between the two. The neglected contribution, which appears at NNLO for the first time, is colo...
متن کاملDominant NNLO Corrections to Four-Fermion Production at the WW Threshold
The production of W -boson pairs at electron-positron colliders is a process of crucial relevance for a precise determination of the W mass. If the International Linear Collider will measure the total cross section at the per-mille level [2], a direct reconstruction of the W -decay products will allow to reach a 10 MeV accuracy on the determination of the W mass [3]. A higher precision could be...
متن کاملOverview of Nnlo Qcd Corrections
We discuss the motivation for making predictions for jet cross sections at next-to-next-to-leading order. I describe the theoretical ingredients needed for such a calculation and briefly review the progress in the field. In the last decade there has been enormous progress in using perturbative QCD to predict and describe events containing jets. At the simplest lowest-order (LO) level, each jet ...
