We have performed a search for a fermiophobic Higgs boson in tri-photon events. The study has been performed on 0.83 fb-1 of data collected with the DZero detector at the Tevatron collider, the world's highest energy accelerator. The study was motivated by the recent phenomenological study that suggests that at presently attained energies and statistics new Higgs production mechanisms become experimentally accessible. All backgrounds were estimated from the data in a self consistent manner. We observed zero tri-photon events and expected 0.5 +/-0.2 from the Standard Model processes. Therefore, we set 95% CL upper limit on the higgs production cross-section which is 25.3 fb-1. This is the most stringent limit on the considered class of models today.

Download Search for the Standard Model Higgs Boson Decaying Into Two Photons in Pp Collisions at Sqrt(s) Book in PDF, ePub and Kindle
A search for a Higgs boson decaying into two photons is described. The analysis is performed using a dataset recorded by the CMS experiment at the LHC from pp collisions at a centre-of-mass energy of 7 TeV, which corresponds to an integrated luminosity of 4.8 inverse femtobarns. Limits are set on the cross section of the standard model Higgs boson decaying to two photons. The expected exclusion limit at 95% confidence level is between 1.4 and 2.4 times the standard model cross section in the mass range between 110 and 150 GeV. The analysis of the data excludes, at 95% confidence level, the standard model Higgs boson decaying into two photons in the mass range 128 to 132 GeV. The largest excess of events above the expected standard model background is observed for a Higgs boson mass hypothesis of 124 GeV with a local significance of 3.1 sigma. The global significance of observing an excess with a local significance greater than 3.1 sigma anywhere in the search range 110-150 GeV is estimated to be 1.8 sigma. More data are required to ascertain the origin of this excess.

Download Search for a Higgs Boson Decaying Into $\gamma*̂\gamma\to\ell\ell\gamma$ with Low Dilepton Mass in Pp Collisions at $\sqrt{s} Book in PDF, ePub and Kindle
Our search is described for a Higgs boson decaying into two photons, one of which has an internal conversion to a muon or an electron pair (ll?). The analysis is performed using proton–proton collision data recorded with the CMS detector at the LHC at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 fb-1. The events selected have an opposite-sign muon or electron pair and a high transverse momentum photon. No excess above background has been found in the three-body invariant mass range 120 mll? 150 GeV, and limits have been derived for the Higgs boson production cross section times branching fraction for the decay H → ?*? → ll?, where the dilepton invariant mass is less than 20 GeV. A Higgs boson with mH=125 GeV has a 95% confidence level (CL) exclusion observed (expected) limit is 6.7 (5.9sup+2.8/supsub-1.8/sub ) times the standard model prediction. Additionally, an upper limit at 95% CL on the branching fraction of H → (J/?)? for the 125 GeV Higgs boson is set at 1.5 × 10
