Subsequently I derive bounds on the + flavour--off--diagonal elements of the squark mass matrices by requiring that the + radiative corrections to + the CKM elements do not exceed the experimental values. The constraints on + the associated dimensionless quantities $\delta^{d\,LR}_{ij}$, $j>i$, are + stronger than the bounds from flavour-changing neutral current (FCNC) + processes if gluino and squarks are heavier than 500$\,\gev$. The + results imply that it is still possible to generate all observed flavour + violation from the soft supersymmetry-breaking terms without conflicting + with present-day data on FCNC processes. Therefore we reappraise the idea that onl + y $Y^q_{33}$ + is different from zero at tree-level and all other Yukawa couplings are generated + radiatively. This model solves the SUSY flavour as well as the SUSY CP problem. The + presented results are published in \cite{Crivellin:2008mq}. + + |**Andreas Crivellin**  | + |**     To appear in the proceedings of 44th Rencontres de Moriond EW 2009: Electroweak Interactions and Unified Theories, La Thuile, Italy, 7-14 Mar 2009. **  | + | {{preprints:2009:ttp09-14.pdf|PDF}} {{preprints:2009:ttp09-14.ps|PostScript}} [[http://arxiv.org/abs/0905.3130|arXiv]]   | + | |
