| 英文摘要 | To ascertain the new boson with mass near 125 GeV observed recently by ATLAS and CMS Collaborations to be the Standard Model Higgs, and to determine its intrinsic properties, more measurements on its various decay channels are still necessary. In this work we reanalyze the processes of the Standard Model Higgs radiative decays to lepton pairs. We find that when photon and leptons are hard, that is possessing energies larger than 1 GeV, the branching fractions of H -> l (l) over bar gamma (l = e or mu) processes are about two-thirds of the H -> mu(+)mu(-) process. Since the lepton pair yields of the radiative processes mainly come from the Z-boson conversion, which will greatly suppress the backgrounds, we believe the signal should be observable in presently accumulated data or in the next run of the LHC experiment, provided the Standard Model Higgs is indeed light.
