Next-to-leading-order temperature corrections to correlators in QCD.

Corrections of order T 4 to vector and axial current correlators in QCD at a finite temperature T < Tc are obtained using dispersion relations for the amplitudes of deep inelastic scattering on pions. Their relation with the operator product expansion is presented. An interpretation of the results in terms of T -dependent meson masses is given: masses of ρ and a1 start to move with temperature ...

Next-to-Next-to-Leading Order QCD Corrections to the Photon’s Parton Structure

The next-to-next-to-leading order (NNLO) corrections in massless perturbative QCD are derived for the parton distributions of the photon and the deep-inelastic structure functions F γ 1 and F γ 2 . We present the full photonic coefficient functions at order ααs and calculate the first six even-integer moments of the corresponding O(ααs ) photon-quark and photon-gluon splitting functions togethe...

Top mass effects in Higgs production at next-to-next-to-leading order QCD: virtual corrections

Top quark mass suppressed terms are calculated for the virtual amplitude for Higgs production in gluon fusion at three-loop level, i.e. O(α3 s ). The method of asymptotic expansions in its automated form is used to evaluate the first three non-vanishing orders in terms of M H /M t , where the first order corresponds to the known results of the effective Lagrangian approach.

Ellis-Jaffe sum rule: The estimates of the next-to-next-to-leading-order QCD corrections.

The procedure of the estimates of the higher-order perturbative QCD corrections to the physical quantities is generalized to the case when the quantities under consideration obey the renormalization group equations with the corresponding anomalous dimension functions. This procedure is used to estimate the α s-corrections to the singlet part of the Ellis-Jaffe sum rule for f = 3 numbers of flav...

Next-to-next-to-leading order soft and virtual corrections for QCD, Higgs and SUSY processes

I review recent advances in the calculation of higher-order soft-gluon corrections for a variety of QCD, Higgs, and SUSY processes in hadron colliders. A unified approach and master formulas for next-to-next-to-leading order soft and virtual corrections are discussed. I present some applications of the formalism to top quark pair production at the Tevatron and the LHC, top production via anomal...
