Available in PDF, EPUB and Kindle. Book excerpt: 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]
