We compute the next-to-leading order (NLO) QCD corrections to the gluon-fusion subprocess of diphoton-plus-jet production at the LHC. We compute fully differential distributions by combining two-loop virtual corrections with one-loop real radiation using antenna subtraction to cancel infrared divergences. We observe significant corrections at NLO which demonstrate the importance of combining these corrections with the quark-induced diphoton-plus-jet channel at next-to-next-to-leading order (NNLO).

在 LHC 上通过胶子聚变对双光子加射流生产进行次领先的 QCD 校正

我们计算了 LHC 上双光子加射流生产的胶子聚变子过程的次前序 (NLO) QCD 校正。我们通过使用天线减法来消除红外发散,将双环虚拟校正与单环真实辐射相结合来计算全差分分布。我们在 NLO 观察到显着的修正,这证明了将这些修正与夸克诱导的双光子加射流通道以紧邻紧邻前导阶 (NNLO) 相结合的重要性。
