The Higgs-boson decay h -> gamma l+ l- for various lepton states l = (e, mu,tau) is analyzed. The differential decay width and forward-backward asymmetryare calculated as functions of the dilepton invariant mass in a model where theHiggs boson interacts with leptons and quarks via a mixture of scalar andpseudoscalar couplings. These couplings are partly constrained from data on thedecays to leptons, h -> l+ l-, and quarks h -> q \bar{q} (where q = (c, b)),while the Higgs couplings to the top quark are chosen from the two-photon andtwo-gluon decay rates. Nonzero values of the forward-backward asymmetry willmanifest effects of new physics in the Higgs sector. The decay width andasymmetry integrated over the dilepton invariant mass are also presented.
