Investigation of the radiative decay b!sg in the 3-4-1-1 model

Nguyen Tuan Duy and Do Thi Huong

We investigate the branching ratio of the radiative decay b!sg in the 3-4-1-1 model with arbitrary charge parameters p;q. We show that the new Higgs bosons, H1, and the new gauge bosons Wq;p 13;14 ;W(q+1);(p+1) 23;24 ;Z2;3 contribute to this decay. Of these sources, the main contribution comes from the interaction of the singly-charged Higgs boson. If the spontaneous breaking of the gauge group symmetry down to the electroweak group is around a few TeVs, the predictions for the branching ratio Br(b!sg) and meson mixing are consistent with experimental constraints. Keywords: radiative corrections; models beyond the standard model; dark matter.
