$h \rightarrow γγ$ excess and Dark Matter from Composite Higgs Models    [PDF]

Mikael Chala
Composite Higgs Models are very appealing candidates for a natural realization of electroweak symmetry breaking. Non minimal models could explain the recent Higgs data from ATLAS, CMS and Tevatron experiments, including the excess in the amount of diphoton events, as well as provide a natural dark matter candidate. In this article, we study a Composite Higgs model based on the coset $SO(7)/G2$. In addition to the Higgs doublet, one $SU(2)_L$ singlet of electric charge one, $\kappa^\pm$, as well as one singlet $\eta$ of the whole Standard Model group arise as pseudo-Goldstone bosons. $\kappa^\pm$ and $\eta$ can be responsible of the diphoton excess and dark matter respectively.
