Weak Decays Beyond Leading Logarithms
Gerhard Buchalla, Andrzej J. Buras, Markus E. Lautenbacher
We review the present status of QCD corrections to weak decays beyond the leading logarithmic approximation including particle-antiparticle mixing and rare and CP violating decays.…
Theoretical Review of B-Physics
Andrzej J. Buras
We review several aspects of B-Physics. In particular we discuss: i) The theoretical framework for B-decays, ii) Weak decays beyond leading logarithms, iii) Standard analysis of th…
A Determination of the CKM-angle using Mixing-induced CP Violation in the Decays and
Andrzej J. Buras, Robert Fleischer
We present a method of determining the CKM-angle by performing simultaneous measurements of the mixing-induced CP asymmetries of the decays and $B_d\to K^0\bar K…
Towards the Control over Electroweak Penguins in Nonleptonic B-Decays
Andrzej J. Buras, Robert Fleischer
We present strategies for determining electroweak penguins from experimental data. Using the CKM-angle as one of our central inputs and making some reasonable approximations, w…
Theoretical Progress in K and B Decays
Andrzej J. Buras
We review several aspects of the recent theoretical progress in K and B decays including the impact of the top quark discovery on rare and CP violating decays. In particular we sum…
Rare Decays, CP Violation and QCD
Andrzej J. Buras
We discuss several aspects of rare decays and CP violation in the standard model including the impact of the recent top quark discovery. In particular we review the present status…
Effective Hamiltonian for $B \ra X_s e^+ e^-$ Beyond Leading Logarithms in the NDR and HV Schemes
A. J. Buras, M. Muenz
We calculate the next-to-leading QCD corrections to the effective Hamiltonian for \Bsee in the NDR and HV schemes. We give for the first time analytic expressions for the Wilson Co…
