Search for Narrow Diphoton Resonances and for gamma-gamma+W/Z Signatures in p\bar p Collisions at sqrt(s)=1.8 TeV
arXiv:hep-ex/0105066 · doi:10.1103/PhysRevD.64.092002
Abstract
We present results of searches for diphoton resonances produced both inclusively and also in association with a vector boson (W or Z) using 100 pb^{-1} of p\bar p collisions using the CDF detector. We set upper limits on the product of cross section times branching ratio for both p\bar p\toγγ+ X and p\bar p\toγγ+ W/Z. Comparing the inclusive production to the expectations from heavy sgoldstinos we derive limits on the supersymmetry-breaking scale sqrt{F} in the TeV range, depending on the sgoldstino mass and the choice of other parameters. Also, using a NLO prediction for the associated production of a Higgs boson with a W or Z boson, we set an upper limit on the branching ratio for H\toγγ. Finally, we set a lower limit on the mass of a `bosophilic' Higgs boson (e.g. one which couples only to γ, W, and Z$ bosons with standard model couplings) of 82 GeV/c^2 at 95% confidence level.
