B -> pi pi, New Physics in B -> pi K and Implications for Rare K and B Decays
Andrzej J. Buras, Robert Fleischer, Stefan Recksiegel +1
The measured B -> pi pi, pi K branching ratios exhibit puzzling patterns. We point out that the B -> pi pi hierarchy can be nicely accommodated in the Standard Model (SM) through n…
epsilon'/epsilon at the NLO: 10 Years Later
Andrzej J. Buras, Matthias Jamin
During the last four years several parameters relevant for the analysis of the CP-violating ratio epsilon'/epsilon improved and/or changed significantly. In particular, the experim…
Petite Unification of Quarks and Leptons: Twenty Two Years After
Andrzej J. Buras, P. Q. Hung
A recent surge of interest in the {\em early} unification of quarks and leptons, has prompted us to revive a paper \cite{HBB} written twenty two years ago. We provided there a gene…
The Impact of Universal Extra Dimensions on the Unitarity Triangle and Rare K and B Decays
Andrzej J. Buras, Michael Spranger, Andreas Weiler
We calculate the contributions of the Kaluza-Klein (KK) modes to the K_L-K_S mass difference ΔM_K, the parameter ε_K, the B^0_{d,s}-\bar B^0_{d,s} mixing mass differences ΔM_{d,s}…
