A search for new physics in the channel p[anti p][yields][gamma][gamma]jj has been studied. In some extended Higgs models, a light neutral scalar Higgs boson is produced with suppressed couplings to fermions and standard model(SM) strength couplings to vector bosons(bosonic Higgs), thus enhancing the H[yields][gamma][gamma] channel. We required one photon in the event with E[sup[gamma]][sub T]> 20 GeV, [vert-bar][eta][sup[gamma]][vert-bar]1.1 or 1.5[vert-bar][eta][sup[gamma]][vert-bar]2.0 and a second photon with E[sup[gamma]][sub T] 15 GeV, [vert-bar][eta][sup[gamma]][vert-bar]1.1 or 1.5[vert-bar][eta][sup[gamma]][vert-bar]

A search for new physics in the channel p{anti p} →??jj has been studied. In some extended Higgs models, a light neutral scalar Higgs boson is produced with suppressed couplings to fermions and standard model(SM) strength couplings to vector bosons(bosonic Higgs), thus enhancing the H →?? channel. We required one photon in the event with E{sup?}{sub T}> 20 GeV, {vert_bar}?{sup?}{vert_bar} 1.1 or 1.5 {vert_bar}?{sup?}{vert_bar} 2.0 and a second photon with E{sup?}{sub T} 15 GeV, {vert_bar}?{sup?}{vert_bar}

The authors present results of a search for diphoton resonances produced inclusively and in association with a vector boson using 100 pb[sup[minus]1] of p[anti p] collisions using the CDF detector. They set upper limits on the product of cross section times branching ratio for p[anti p][r-arrow][gamma][gamma][r-arrow] X and p[anti p][r-arrow][gamma][gamma][r-arrow] W/Z. Using a NLO prediction for associated production cross section of a Higgs with a vector boson (W or Z), they set an upper limit on the branching ratio for H[r-arrow][gamma][gamma]. They set a lower limit on the mass of a'bosophilic' Higgs boson (e.g. one which couples only to[gamma], W, and Z bosons with Standard Model couplings) of 82 GeV/c[sup 2] at 95% C.L.

The authors present results of a search for diphoton resonances produced inclusively and in association with a vector boson using 100 pb−1 of p{anti p} collisions using the CDF detector. They set upper limits on the product of cross section times branching ratio for p{anti p} →?? → X and p{anti p} →?? → W/Z. Using a NLO prediction for associated production cross section of a Higgs with a vector boson (W or Z), they set an upper limit on the branching ratio for H →??. They set a lower limit on the mass of a b̀osophilic ̀Higgs boson (e.g. one which couples only to?, W, and Z bosons with Standard Model couplings) of 82 GeV/c2 at 95% C.L.
