Fiducial cross sections for the lepton-pair-plus-photon decay mode in Higgs production up to NNLO QCD

Chen, X. and Gehrmann, T. and Glover, E. W. N. and Huss, A. (2022) 'Fiducial cross sections for the lepton-pair-plus-photon decay mode in Higgs production up to NNLO QCD.', Journal of high energy physics., 2022 (53).

Abstract

The rare three-body decay of a Higgs boson to a lepton-antilepton pair and a photon is starting to become experimentally accessible at the LHC. We investigate how higher-order QCD corrections to the dominant gluon-fusion production process impact on the fiducial cross sections in this specific Higgs decay mode for electrons and muons. Corrections up to NNLO QCD are found to be sizeable. They are generally uniform in kinematical variables related to the Higgs boson, but display several distinctive features in the kinematics of its individual decay products.
