In non-minimal supersymmetric models, novel effects of flavour violation may occur and the flavour structure in the squark sector cannot be directly deduced from the trilinear Yukawa couplings of the fermion and Higgs supermultiplets. Additional sources of flavour violation have to be included in the squark mass matrices. We establish the parameter space regions allowed/favoured by low-energy, electroweak precision, and cosmological data, and define several constrained supersymmetry breaking scenarios with non-minimal flavour violation for which we study the favour structure of the squark sector in details. We present the cross sections for SUSY particle pair production processes as well as their decay widths, and show their dependence on the off-diagonal mass matrix elements in the experimentally allowed favoured ranges.
