Abstract
A search has been carried out for events in the channel p(p)over-bar --> ga mma gamma + 2 jets. Such a signature can characterize the production of a n onstandard Higgs boson together with a W or Z boson. We refer to this nonst andard Higgs, having standard model couplings to vector bosons but no coupl ing to fermions, as a "bosonic Higgs." With the requirement of two high tra nsverse energy photons and two jets, the diphoton mass (m(gamma gamma)) dis tribution is consistent with expected background. A 90 (95)% confidence lev el (C.L.) upper limit on the cross section as a function of mass is calcula ted, ranging from 0.60 (0.80) pb for m(gamma gamma) = 65 GeV/c(2) to 0.26 ( 0.34) pb for m(gamma gamma) = 150 GeV/c(2), corresponding to a 95% C.L. low er limit on the mass of a bosonic Higgs of 78.5 GeV/c(2).
