SU(3) Predictions for Weak Decays of Doubly Heavy Baryons -- including SU(3) breaking terms
David A. Egolf, Roxanne P. Springer, Joerg Urban
We find expressions for the weak decay amplitudes of baryons containing two b quarks (or one b and one c quark -- many relationship are the same) in terms of unknown reduced matrix…
Neutral Higgs boson contributions to the decays B_{d,s}->mu^+ mu^- in the MSSM at large tan[beta]
Joerg Urban
It is well known that the Minimal Supersymmetric Standard Model (MSSM) can enhance Br[B_{d,s}->mu^+ mu^-] by orders of magnitude, even if we assume the Cabibbo-Kobayashi-Maskawa (C…
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…
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 ->…
Master Formulae for Delta F=2 NLO-QCD Factors in the Standard Model and Beyond
Andrzej J. Buras, Sebastian Jager, Joerg Urban
We present analytic formulae for the QCD renormalization group factors relating the Wilson coefficients C_i(mu_t) and C_i(mu), with mu_t = O(m_t) and mu < mu_t, of the Delta F=2 di…
Two-Loop QCD Anomalous Dimensions of Flavour-Changing Four-Quark Operators Within and Beyond the Standard Model
Andrzej J. Buras, Mikolaj Misiak, Joerg Urban
We calculate the two-loop QCD anomalous dimension matrix (ADM) gamma^(1)_NDR in the NDR-MSbar scheme for all the flavour-changing four-quark dimension-six operators that are releva…
