Status of the B -> pi K puzzle and its relation to Bs -> phi pi and Bs -> phi rho decays
Abstract
Some discrepancies between theory and experiment in the B -> pi K decays suggest the possibility of a new physics contribution with the structure of an electroweak penguin amplitude. If such a scenario is realised in nature, the branching ratios of the decays Bs -> phi pi and Bs -> phi rho can be enhanced by about one order of magnitude. We review and update the current status of the B -> pi K puzzle and its implications for the decays Bs -> phi pi and Bs -> phi rho.
