Metastability of an Extended Higgs Model

الملخص EN

We consider a singlet extended supersymmetric Higgs model.

In the limit of tanβ=1 it is possible to unravel the vacuum structure of this model analytically.

We span the parameter space of the model.

Specially we consider configurations in this space for a Higg’s mass of 125 GeV.

We provide a detailed discussion of the issue of metastability of this model.
