B -> pi pi, New Physics in B -> pi K and Rare K and B Decays
Andrzej J. Buras, Robert Fleischer, Stefan Recksiegel +1
We summarize a recent strategy for a global analysis of the B -> pi pi, pi K systems and rare decays. We find that the present B -> pi pi and B -> pi K data cannot be simultaneousl…
The B -> pi pi,pi K Puzzles in the Light of New Data: Implications for the Standard Model, New Physics and Rare Decays
Andrzej J. Buras, Robert Fleischer, Stefan Recksiegel +1
Recently, we developed a strategy to analyse the B -> pi pi,pi K data. We found that the B -> pi pi measurements can be accommodated in the Standard Model (SM) through large non-fa…
Finite energy sum rules for the vector current: the strange quark mass
Markus Eidemuller, Matthias Jamin, Felix Schwab
We determine the strange quark mass in the framework of finite energy sum rules from the vector current channel. The theoretical contributions are calculated in contour improved pe…
Strange Quark Mass Determination From Sum Rules For Hadronic Tau-Decays
Felix Schwab
We discuss the ratio of hadronic to leptonic tau-decays, that can be expanded in an operator product expansion. The sensitivity to the strange mass is increased, if only the flavor…
