Charming penguins in B -> PP decays and the extraction of gamma

Abstract

It is shown that inclusion of charming penguins of the size suggested by short-distance dynamics may shift down by $10^o-15^o$ the value of $\gamma$ extracted via the overall fit to the $B\to PP$ branching ratios. A substantial dependence of the fit on their precise values is found, underscoring the need to improve the reliability of data.
