Status of the B -> pi K puzzle and its relation to Bₛ -> phi pi and Bₛ -> phi rho decays

Original · EN
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.
