Search for a low-mass neutral Higgs boson with suppressed couplings to fermions using events with multiphoton final states

Abstract: A search for a Higgs boson with suppressed couplings to fermions, hf, assumed to be the neutral, lower-mass partner of the Higgs boson discovered at the Large Hadron Collider, is reported. Such a Higgs boson could exist in extensions of the standard model with two Higgs doublets, and could be produced via p¯p?H±hf?W*hfhf?4?+X, where H± is a charged Higgs boson. This analysis uses all events with at least three photons in the final state from proton-antiproton collisions at a center-of-mass energy of 1.96 TeV collected by the Collider Detector at Fermilab, corresponding to an integrated luminosity of 9.2??fb-1. No evidence of a signal is observed in the data. Values of Higgs-boson masses between 10 and 100??GeV/c2 are excluded at 95% Bayesian credibility.
