Search for a Higgs boson decaying to four photons through light CP-odd scalar coupling using \lumifull of $7~\mathrm{TeV}$ $pp$ collision data taken with ATLAS detector at the LHC
In some extensions of the Standard Model, such as MCHM or NMSSM, the Higgs boson can couple to light CP-odd scalar particles. This document presents a study of a possible contribution to a Higgs boson signal in the $H\to\gamma\gamma$ channel due to $H\to a a$ decays, where $a$ is a light CP-odd scal...
