Description

Production in association with a vector boson $V$ is a distinctive mode of production for a Higgs boson $H$ without tree-level couplings to fermions, known as a fermiophobic Higgs boson. We focus on $HV$ associated production with $H$ decay into a pair of photons, and $V$ into a pair of jets, with the goal of distinguishing a fermiophobic Higgs boson from the standard model Higgs boson. Performing a simulation of the signal and pertinent QCD backgrounds, and using the same event selection cuts employed by the LHC ATLAS collaboration, we argue that existing LHC data at 7 TeV with 4.9~fb$^{-1}$ of integrated luminosity may contain evidence for a fermiophobic Higgs boson near 125 GeV at about 1.9 standard deviation signal significance $1.9\sigma$. At 8 TeV the same analysis shows that associated production could yield $3\sigma$ significance with 10~fb$^{-1}$ of data.
