|Delta F| = 1 Nonleptonic Effective Hamiltonian in a Simpler Scheme
Konstantin Chetyrkin, Mikolaj Misiak, Manfred Muenz
We consider |ΔF| = 1 (F = S,C or B) nonleptonic effective hamiltonian in a renormalization scheme which allows to consistently use fully anticommuting gamma_5 at any number of loop…
Beta functions and anomalous dimensions up to three loops
Konstantin Chetyrkin, Mikolaj Misiak, Manfred Muenz
We derive an algorithm for automatic calculation of perturbative -functions and anomalous dimensions in any local quantum field theory with canonical kinetic terms. The infrared…
Weak Radiative B-Meson Decay Beyond Leading Logarithms
Konstantin Chetyrkin, Mikolaj Misiak, Manfred Munz
We present our results for three-loop anomalous dimensions necessary in analyzing decay at the next-to-leading order in QCD. We combine them with other recently calcul…
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…
Two-loop mixing of dimension-five flavor-changing operators
M. Misiak, M. Muenz
We calculate the two-loop QCD mixing of the dimension-five flavor-changing operators that arise in the Standard Model after integrating out the , and Higgs bosons and the to…
The Strange Quark Mass from QCD Sum Rules
Matthias Jamin, Manfred M"unz
The strange quark mass is calculated from QCD sum rules for the divergence of the vector as well as axial-vector current in the next-next-to-leading logarithmic approximation. The…
Direct CP Violation in K_L --> π^0 e^+e^- Beyond Leading Logarithms
A. J. Buras, M. E. Lautenbacher, M. Misiak +1
We analyze the direct CP violation in the rare decay K_L --> Pi^0 e+e- with QCD effects taken into account consistently in the next-to-leading order. We calculate the two-loop mixi…
Current correlators to all orders in the quark masses
M. Jamin, M. Muenz
The contributions to the coefficient functions of the quark and the mixed quark-gluon condensate to mesonic correlators are calculated for the first time to all orders in the quark…
