Description
We compute the finite renormalisation of the CKM matrix induced by
gluino-squark diagrams in the MSSM with non-minimal sources of flavour
violation. Stringent bounds on the flavour-off-diagonal elements of the
squark mass matrices are obtained by requiring that the radiative
corrections to the CKM elements do not exceed the experimental values. Our
bounds on several flavour-changing trilinear terms are stronger than those
from FCNC processes if gluino and squarks are heavier than roughly 500
GeV. We point out that it is possible to generate the CKM matrix and the
quark masses of the first two generations radiatively from soft
SUSY-breaking terms without violating present-day FCNC constraints.
