2006:  1 with b  s Penguins Smaller than b  ccs in all of 9 modes Smaller than b  ccs in all of 9 modes Theory tends to predict positive shifts (originating from phase in Vts) Naïve average of all b  s modes sin2  eff = 0.52 ±  deviation between penguin and tree (b  s) (b  c) Naïve average of all b  s modes sin2  eff = 0.52 ±  deviation between penguin and tree (b  s) (b  c)

~s ~ x How to make  small? Tune the squark mixing terms is there enough freedom to do this? Make the squark masses degenerate invoke a GIM-like mechanism Make the SUSY mass scale very high (~few TeV) not much fun for LHC experimenters b g ~
