ATLAS Collaboration. 2016. Search for a Low-Mass Neutral Higgs Boson with Suppressed Couplings to Fermions Using Events with Multiphoton Final States. Phys. Rev. D 93, no. 11. doi:10.1103/physrevd.93.112010.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 pp¯→H±hf→W∗hf hf→4γ + 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/c 2 are excluded at 95% Bayesian credibility.Other Sources
