Searching for anomalous Higgs couplings in peripheral heavy ion collisions at the LHC

Abstract

We investigate the sensitivity of the heavy ion mode of the LHC to anomalous Higgs boson couplings to photons, H gamma gamma, through the analysis of the processes gamma gamma --> b (b) over bar and gamma gamma --> gamma gamma in peripheral heavy ion collisions. We suggest cuts to improve the signal over background ratio and determine the capability of LHC to impose bounds on anomalous couplings by searching for a Higgs boson signal in these modes.
