The Messenger Sector of SUSY Flavour Models and Radiative Breaking of
Flavour Universality    [PDF]

Lorenzo Calibbi, Zygmunt Lalak, Stefan Pokorski, Robert Ziegler

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.
