Description

We study the effect of squark generation mixing on squark and gluino production and decays at LHC in the Minimal Supersymmetric Standard Model (MSSM) with focus on mixing between second and third generation squarks. Taking into account the constraints from B-physics we show that various regions in parameter space exist where decays of squarks and/or gluinos into flavour violating final states can have large branching ratios of up to ~ 40%. Here we consider both fermionic and bosonic final states. Rates of the corresponding signals, e.g. pp -> t t cbar cbar missing-E_T X, can be significant at LHC(14 TeV). We find that the inclusion of flavour mixing effects can be important for the search of squarks and gluinos and the determination of the underlying model parameters of the MSSM.
