Constraints on $\gamma$ and Strong Phases from $B\to \pi K$ Decays

Andrzej J. Buras, Robert Fleischer

As we pointed out recently, the neutral decays $B_d\to {\pi }^{\mp }{K}^{\pm }$ and $B_d\to {\pi }^{0}K$ may provide non-trivial bounds on the CKM angle $\gamma$. Here we reconsider this approach in the lig…
