Measuring B -> tau nu and B_c -> tau nu at the Z peak
A. G. Akeroyd, Chuan Hung Chen, S. Recksiegel
The measurement of B->tau nu at the B factories provides important constraints on the parameter tan beta/m_H^+- in the context of models with two Higgs doublets. Limits on this dec…
On Puzzles and Non-Puzzles in B -> pi pi, pi K Decays
Robert Fleischer, Stefan Recksiegel, Felix Schwab
Recently, we have seen interesting progress in the exploration of CP violation in B^0_d -> pi^+ pi^-: the measurements of mixing-induced CP violation by the BaBar and Belle collabo…
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…
Purely Leptonic B decays at High Luminosity e+e- B factories
A. G. Akeroyd, S. Recksiegel
High Luminosity upgrades of the KEK-B collider are being discussed. We consider the role of the purely leptonic decays B^\pm -> l^\pm nu and B^0 -> l+l- in motivating such an upgra…
Direct CP Asymmetry of B -> X_d γin the effective SUSY model
A. G. Akeroyd, Y. -Y. Keum, S. Recksiegel
We investigate the effect of supersymmetric CP violating phases on the inclusive decay B\to X_dγ. Although such a decay contains a large background from B\to X_sγ, if isolated it m…
