The B-->pi K Puzzle and Supersymmetry

Understand

At present, there are discrepancies between the measurements of several observables in B-->pi K decays and the predictions of the standard model (the ``B-->pi K puzzle'').

• Although the effect is not yet statistically significant -- it is at the level of $\gsim 3\sigma$ -- it does hint at the presence of new physics.
• In this paper, we explore whether supersymmetry (SUSY) can explain the B-->pi K puzzle.
• In particular, we consider the SUSY model of Grossman, Neubert and Kagan (GNK).
