Abstract

We study the effect of squark generation mixing on squark production and decays at the LHC in the Minimal Supersymmetric Standard Model (MSSM). We show that the effect can be very large despite the very strong constraints on quark flavour violation (QFV) from experimental data on B mesons. We find that the two lightest up‐type squarks
can have large branching ratios for the decays into
and
at the same time, leading to QFV signals ‘
