Abstract:
We present the results of the search for the associated production of the Higgs boson with a pair, using for the first time the events where the Higgs boson decays to two photons.
To maximize acceptance and sensitivity to such a small signal, we device two different sets of event selection criteria, optimized for leptonic and hadronic decays. We analyze 19.6\,fb of 8\,TeV collisions and found no significant excess over the background-only predictions. We thus proceed to set an observed (expected) 95\% confidence level upper limit on the production cross section times of 5.4 (5.3) times the standard model value, corresponding to 1.6~fb, for a Higgs boson of \,GeV.Note:
