NNLO QCD Corrections to the B̄ → X s γ Matrix Elements Using Interpolation in m c
One of the most troublesome contributions to the NNLO QCD corrections to B̄ → Xsγ originates from three-loop matrix elements of four-quark operators. A part of this contribution that is proportional to the QCD beta-function coefficient β0 was found in 2003 as an expansion in mc/mb. In the present paper, we evaluate the asymptotic behaviour of the complete contribution for mc ≫ mb/2. The asymptot...

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 ...
متن کاملOne-loop QCD corrections to quark scattering at NNLO∗
We present the O(α s) virtual QCD corrections to unlike-quark qq̄ → q q̄ and like-quark scattering qq̄ → qq̄ due to the interference of one-loop amplitudes with one-loop amplitudes. The structure of the infrared divergences agrees with that predicted by Catani. The results are expressed in an analytic form so that the relevant expressions for crossed scattering processes can be obtained in a straig...
متن کاملA Master Formula for Nnlo Soft and Virtual Qcd Corrections
with σ the physical cross section, σ̂ the perturbatively calculable hard scattering factor, and φf/hi the parton distribution for parton f in hadron hi. The partonic hard-scattering factors σ̂ include soft and virtual corrections, arising from soft-gluon emission and loop diagrams, which manifest themselves as plus distributions and delta functions with respect to a kinematical variable xth that ...
