Search for Narrow Diphoton Resonances and for gamma-gamma+W/Z Signatures in p p Collisions at sqrt(s)=1.8 TeV

الأصل · EN

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 p collisions using the CDF detector. We set upper limits on the product of cross section times branching ratio for both p p→γγ+ X and p p→γγ+ W/Z. Comparing the inclusive production to the expectations from heavy sgoldstinos we derive limits on the supersymmetry-breaking scale sqrtF 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→γγ. 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/c² at 95% confidence level.
