We have 3 theoretical models (frameworks) where our final state is applicable: | We have 3 theoretical models (frameworks) where our final state is applicable: | ||
- | Theory 1: Werner | + | Theory 1: Werner: in the NMSSM the lightest neutralinos/chargino can be mainly the MSSM higgsinos. |
+ | In case of a large singlet-doublet couplings, one gets sizable cross section for | ||
+ | pp -> chi chi H_1. Here chi chi is the summation over all higgsinos which are mass degenerate within a few | ||
+ | GeV. | ||
+ | |||
+ | The second interesting process ist pp -> H_3 -> H_1 H_1 where the H_3 is the heaviest neutral Higgs boson. | ||
+ | |||
+ | The third is pp -> t t -> W b H+ b where H+ decays into W H_1 and the later to gamma gamma. | ||

+ | |||
+ | 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. | ||
