Power corrections to the production of a prompt photon in association with a jet in the N-jettiness slicing scheme at NLO QCD
Abstract
We compute the next-to-leading-power corrections in the N-jettiness variable to the production of a prompt photon and a jet at next-to-leading order in perturbative QCD in the q q annihilation channel. We employ the k jet algorithm and assume that the N-jettiness value divided by the jet transverse momentum is the smallest parameter in the problem; in particular it should be small compared to the jet radius R.
