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…
Another Look at the Flavour Structure of the Littlest Higgs Model with T-Parity
Monika Blanke, Andrzej J. Buras, Anton Poschenrieder +4
We discuss the mixing matrix V_Hd that describes the charged and neutral current interactions between ordinary down-quarks and up- and down-mirror quarks in the Littlest Higgs Mode…
New Aspects of B -> pi pi, pi K and their Implications for Rare Decays
Andrzej J. Buras, Robert Fleischer, Stefan Recksiegel +1
We analyse the B -> pi pi, pi K modes in the light of the most recent B-factory data, and obtain the following new results: (i) the B0 -> pi+ pi-, pi- K+ modes prefer gamma=(74+-6)…
Electroweak Penguin Hunting Through B -> pi pi, pi K and Rare K and B Decays
Andrzej J. Buras, Robert Fleischer, Stefan Recksiegel +1
The decays with significant electroweak penguin contributions show a puzzling pattern. We explore this " puzzle" through a systematic strategy. The starting point,…
b -> d Penguins: CP Violation, General Lower Bounds on the Branching Ratios and Standard Model Tests
Robert Fleischer, Stefan Recksiegel
With the wealth of new data from the B-factories, b -> d penguin decays become available for study, in addition to their b -> s counterparts that have proven an indespensable tool…
