QCD Corrections to B -> X_{d,s} nu nubar, B_{d,s} -> l^+l^-, K -> pi nu nubar and K_L -> mu^+ mu^- in the MSSM
C. Bobeth, A. J. Buras, F. Krüger +1
We compute for the first time QCD corrections to the rare decays B -> X_{d,s} nu nubar, B_{d,s} -> l^+ l^-, K -> pi nu nubar and K_L -> mu^+ mu^-, where l=e or mu, in the context o…
Flavour Physics and CP Violation in the SM
Andrzej J. Buras
We review the main aspects of Flavour Physics and CP Violation in the Standard Model. After presenting a grand view of the field including a Master Formula for weak decays we discu…
, and the angle in the Presence of New Operators
Andrzej J. Buras, Piotr H. Chankowski, Janusz Rosiek +1
We present formulae for the mass differences and in the \BBds systems and for the CP violation parameter which are valid in minimal flavour violation models givin…
What is the (epsilon'/epsilon)_exp Telling Us ?
Andrzej J. Buras, Jean-Marc Gérard
Nature might be kinder than previously thought as far as epsilon'/epsilon is concerned. We show that the recently obtained experimental value for epsilon'/epsilon does not require…
Two-Loop Matrix Element of the Current-Current Operator in the Decay B -> X_s gamma
Andrzej J. Buras, Andrzej Czarnecki, Mikolaj Misiak +1
We evaluate the important two-loop matrix element <s gamma| Q_2 | b> of the operator (cbar gamma^mu P_L b) (sbar gamma_mu P_L b) contributing to the inclusive radiative decay B ->…
Bounds on the Unitarity Triangle, and Decays in Models with Minimal Flavour Violation
Andrzej J. Buras, Robert Fleischer
We present a general discussion of the unitarity triangle from , and in models with minimal flavour violation (MFV), allowing for arbitrary sig…
