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 ...
متن کاملNext-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...
متن کاملEllis-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...
متن کاملEffects of supersymmetric QCD in hadronic Higgs production at next-to-next-to-leading order
An estimate of the next-to-next-to-leading order ~NNLO! supersymmetric QCD effects for Higgs production at hadron colliders is given. Assuming an effective gluon-Higgs interaction, these corrections enter only in terms of process-independent, factorizable terms. We argue that the current knowledge of these terms up to NLO is sufficient to derive the NNLO hadronic cross section within the limita...
متن کاملNext-to-next-to-leading-order logarithmic corrections at small transverse momentum in hadronic collisions
We study the region of small transverse momenta in q&qmacr;- and gg-initiated processes with no colored particle detected in the final state. We present the universal expression of the O(alpha(2)(s)) logarithmically enhanced contributions up to next-to-next-to-leading-order logarithmic accuracy. From there we extract the coefficients that allow the resummation of the large logarithmic contribut...
