Updated constraints on general squark flavor mixing

Abstract

We explore the phenomenological implications on nonminimal flavor violating (NMFV) processes from squark flavor mixing within the minimal supersymmetric standard model (MSSM). We work under the model-independent hypothesis of general flavor mixing in the squark sector, being parametrized by a complete set of dimensionless δijAB (A,B=L,R; i,j=u,c,t or d,s,b; i≠j) parameters. The present upper bounds on the most relevant NMFV processes, together with the requirement of compatibility in the choice of the MSSM parameters with the recent LHC and (g-2)μ data, lead to updated constraints on all squark flavor mixing parameters.
