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-LEADING ORDER CORRECTIONS TO e+e− → FOUR JETS
I present a general purpose Monte Carlo program for calculating the next-to-leading order corrections to arbitrary four-jet quantities in electron-positron annihilation. In the current version of the program, some subleading in color terms are neglected. As an example, I calculate the four-jet rate in the Durham scheme as well as the BengtssonZerwas angular distribution at O(αs) and compare the...
متن کاملSoft and virtual corrections to pp → H + X at next - to - next - to - leading order
The contributions of virtual corrections and soft gluon emission to the inclusive Higgs boson production cross section pp → H +X are computed at next-to-next-to-leading order in the heavy top quark limit. We show that this part of the total cross section is well behaved in the sense of perturbative convergence, with the NNLO corrections amounting to an enhancement of the NLO cross section by ∼ ...
متن کاملAnnihilation to Next-to-leading Order Accuracy *
We discuss the production of two hadrons in e + e − annihilation within the framework of perturbative QCD. The cross section for this process is calculated to next-to-leading order accuracy with a selection of variables that allows the consideration of events where the two hadrons are detected in the same jet. In this configuration we contemplate the possibility that the hadrons come from a dou...
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...
