SUMMARY:Flavoured squark signatures at the LHC\, Theory Seminar (High 
 Energy/Cosmology)\, Gabriel Lee
DESCRIPTION:We present benchmark points for LHC searches from flavored
  gauge mediation models\, in which messenger–matter couplings give f
 lavor-dependent squark masses. Our examples include spectra in which a
  single squark—stop\, scharm\, or sup—is much lighter than all oth
 er colored superpartners\, motivating improved quark flavor tagging at
  the LHC. Many examples feature flavor mixing\; in particular\, large 
 stop–scharm mixing is possible. The correct Higgs mass is obtained i
 n some examples by virtue of the large stop A-term. We also revisit th
 e general flavor and CP structure of the models. Even though the A-ter
 ms can be substantial\, their contributions to EDM’s are very suppre
 ssed\, because of the particular dependence of the A-terms on the mess
 enger coupling. This holds regardless of the messenger-coupling textur
 e. More generally\, the special structure of the soft terms often lead
 s to stronger suppression of flavor- and CP-violating processes\, comp
 ared to naive estimates.
