Search for Non-standard Higgs Boson in Diphoton Events at p pbar Collisions

Abstract

We estimate the attainable limits on the coupling of a non-standard Higgs boson to two photons taking into account the data collected by the Fermilab collaborations on diphoton events. We based our analysis on a general set of dimension--6 effective operators that give rise to anomalous couplings in the bosonic sector of the Standard Model. If the coefficients of all ``blind'' operators are of the same order of magnitude, bounds on the anomalous triple vector-boson couplings can also be obtained.
