Singlet extended standard model in the context of split supersymmetry

Gabelmann, Martin; Mühlleitner, M. Margarete; Staub, Florian

Abstract:
We consider a low-energy effective theory of the next-to-minimal supersymmetric Standard Model by decoupling all scalar states except one Higgs doublet and the complex gauge singlet. The mass spectrum of the resulting singlet extended Standard Model is calculated from two different perspectives: (i) using a matching of the scalar sectors at next-to-leading order and (ii) using the simplified-model approach of calculating the masses in the effective theory at fixed order at the weak scale ignoring any connection to the full theory. Significant deviations between the two methods are found not only in the scalar sector, but also properties of the additional fermions can be very different. Thus, only a small part of the parameter space of the simplified model can be embedded in a well-motivated supersymmetry framework.
