Virtual QCD corrections to gluon-initiated diphoton plus jet production at hadron colliders

چکیده
A bstract We present an analytic computation of the gluon-initiated contribution to diphoton plus jet production at hadron colliders up two loops in QCD. reconstruct form finite remainders from numerical evaluations over fields including all colour contributions. Compact expressions are found using pentagon function basis. provide a fast and stable implementation for colour- helicity-summed interference between one-loop two-loop C++ as part NJet library.

QCD radiative corrections to prompt diphoton production in association with a jet at hadron colliders
We compute the next-to-leading order corrections in αS to prompt diphoton production in association with a jet at hadron colliders. We use a next-to-leading order general-purpose partonic Monte Carlo event generator that allows the computation of a rate differential in the produced photons and hadrons.
متن کاملNLO QCD corrections to ZZ+jet production at hadron colliders
A fully differential calculation of the next-to-leading order QCD corrections to the production of Z-boson pairs in association with a hard jet at the Tevatron and LHC is presented. This process is an important background for Higgs particle and new physics searches at hadron colliders. We find sizable corrections for cross sections and differential distributions, particularly at the LHC. Residu...
متن کاملSecond-order QCD corrections to jet production at hadron colliders: the all-gluon contribution.
We report the calculation of next-to-next-to-leading order QCD corrections in the purely gluonic channel to dijet production and related observables at hadron colliders. Our result represents the first next-to-next-to-leading order calculation of a massless jet observable at hadron colliders, and opens the path towards precision QCD phenomenology with the LHC.
متن کاملThreshold corrections to inclusive jet production at hadron colliders
We compute QCD threshold corrections to the inclusive jet hadro-production process in the softgluon resummation formalism. We expand the resummed results to 1-loop and 2-loop level at next-to-leading logarithmic (NLL) accuracy and compare with the results in the literature. Further, by presenting the transverse momentum distributions of the jet for Tevatron and LHC, we investigate the jet cone ...
متن کاملSUSY–QCD Corrections to Higgs Boson Production at Hadron Colliders
We analyze the next-to-leading order SUSY-QCD corrections to the production of Higgs particles at hadron colliders in supersymmetric extensions of the Standard Model. Besides the standard QCD corrections due to gluon exchange and emission, genuine supersymmetric corrections due to the virtual exchange of squarks and gluinos are present. At both the Tevatron and the LHC, these corrections are fo...
