 +The model consists of a scalar which is pair produced by gauge interactions:​ qq -> H' H', and VBF -> H' H'. At low mass, the kinematically allowed decays are: W gamma (charged) and gamma gamma (neutral).
 +We can start considering a triplet of SU(2)L, with production channels H'+ H'-, and H'+ H'0. We will create a MG file asap.

 +A sample model, with a singlet decaying in VV (but not gamma gamma): [[http://​arxiv.org/​abs/​1502.04718|1502.04718]]. More references to follow soon.
