Renormalization effects on MSSM from a calculable model of strongly coupled hidden sector
Original language description
We investigate renormalization effects on the low energy mass spectrum of the minimal supersymmetric standard model (MSSM), using a calculable model of strongly coupled hidden sector. We model the hidden sector by ${cal N}=2$ supersymmetric quantum chromodynamics with gauge group $SU(2)times U(1)$ and $N_f=2$ matter hypermultiplets, perturbed by a Fayet-Iliopoulos term which breaks the supersymmetry down to ${cal N}=0$ on a meta-stable vacuum. The hidden sector K"{a}hler metric is renormalized, contributing to the MSSM renormalization group flows via gauge mediation. In contrast to perturbative examples of hidden sector renormalization studied in the literature, we find that our strongly coupled model exhibits rather intricate effects on the MSSM soft scalar mass spectrum, depending sensitively on how the hidden sector fields are coupled to the messenger fields.
