Description
We present an extensive analysis of squark and gaugino hadroproduction and decays in
non-minimal flavour violating supersymmetry (SUSY). Within minimal flavour violation,
the flavour violating entries in the squark mass matrices are believed to stem from
the trilinear Yukawa couplings of the fermion and Higgs supermultiplets, resulting in
different renormalizations of the quark and squark mass matrices through
renormalization group running, while within non-minimal flavour violating SUSY,
additional sources of flavour violation are included and the off-diagonal terms of
the mass matrices cannot be simply deduced from the Yukawa couplings alone.
We establish the parameter space regions allowed/favoured by low-energy, electroweak
precision, and cosmological data, and define several constrained supersymmetry
breaking models with non-minimal flavour violation. We present the cross sections for
squark-(anti-)squark/gaugino pair and squark-gaugino associated 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.
