摘要

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 ¯ \( q\overline{q} \) 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.
