More light on Higgs flavor at the LHC: Higgs boson couplings to light quarks through h+γ production

Abstract

Higgs production in association with a photon at hadron colliders is a rare process, not yet observed at the LHC. We show that this process is sensitive to significant deviations of Higgs couplings to first- and second-generation SM quarks (particularly the up type) from their SM values, and we use a multivariate neural network analysis to derive the prospects of the High Luminosity LHC to probe deviations in the up and charm Higgs Yukawa couplings through h+γ production.
