Unitarity Triangle: 2002 and Beyond
Andrzej J. Buras
We describe the present status of the Unitarity Triangle and we give an outlook for its future determinations. We discuss new sets of fundamental flavour parameters and comment bri…
, and in Supersymmetry at Large
A. J. Buras, P. H. Chankowski, J. Rosiek +1
We present an effective Lagrangian formalism for the calculation of flavour changing neutral and charged scalar currents in weak decays including symmetry breaki…
Correlation between Delta M_s and B^0_{s,d} --> mu^+ mu^- in Supersymmetry at Large tan beta
A. J. Buras, P. H. Chankowski, J. Rosiek +1
Considering the MSSM with the CKM matrix as the only source of flavour violation and heavy supersymmetric particles at large , we analyze the correlation between {\it the in…
B -> X_s gamma after completion of the NLO QCD calculations
Andrzej J. Buras, Mikolaj Misiak
Several years ago, Stefan Pokorski, Manfred Muenz and us outlined a program for calculation of the NLO QCD corrections to the weak radiative B meson decay B -> X_s gamma. Very rece…
The CKM Matrix and The Unitarity Triangle: Another Look
Andrzej J. Buras, Fabrizio Parodi, Achille Stocchi
The unitarity triangle can be determined by means of two measurements of its sides or angles. Assuming the same relative errors on the angles and the sides , w…
Completing the NLO QCD calculation of B -> Xs gamma
Andrzej J. Buras, Andrzej Czarnecki, Mikolaj Misiak +1
We evaluate two-loop b -> s gamma matrix elements of all the four-quark operators containing no derivatives. Contrary to previous calculations, no expansion in the mass ratio mc/mb…
