The Messenger Sector of SUSY Flavour Models and Radiative Breaking of Flavour Universality
arXiv:1203.1489 · doi:10.1007/JHEP06(2012)018
Abstract
The flavour messenger sectors and their impact on the soft SUSY breaking terms are investigated in SUSY flavour models. In the case when the flavour scale M is below the SUSY breaking mediation scale M_S, the universality of soft terms, even if assumed at M_S, is radiatively broken. We estimate this effect in a broad class of models. In the CKM basis that effect gives flavour off-diagonal soft masses comparable to the tree-level estimate based on the flavour symmetry.
