These FCNC (Flavor Changing Neutral Current) decays proceed via Z-penguin or W-box diagrams within the Standard Model, and are consequently quite suppressed.
SM predicts a Branching Fraction of 3.8 x 10-6.
Several other theories (multi-Higgs doublet model, minimal super-symmetry (SUSY), etc.) imply an increase in b svv, which invites an investigation of this channel.Previous Analyses For This ModeSemileptonic tag: B(K+)
