Hidden-sector-assisted 125 GeV Higgs boson

In order to significantly raise the mass of the supersymmetry Higgs boson, we consider a radiative correction to it by heavy (similar to 1 TeV) hidden sector fields, which communicate with the Higgs through relatively light messengers (300-500 GeV). The messenger fields (S, (S) over bar) are coupled to the Higgs (y(H)SH(u)H(d), y(H) less than or similar to 0.7) and also to hidden sector fields with a Yukawa coupling of order unity. The hidden sector fields are assumed to be large representations of a hidden gauge group, and so their scalar partner masses can be heavier than other typical soft scalars in the visible sector. Even with a relatively small y(H) (similar to 0.2) or tan beta similar to 10 but without top-stop's considerable contributions, the radiative correction by such hidden sector fields can be enhanced enough to yield the 125 GeV Higgs mass.
