Next-to-Leading Order QCD Corrections to effective Hamiltonians
M. Ciuchini, E. Franco, V. Lubicz +3
The most general QCD next-to-leading anomalous-dimension matrix of all possible four-fermion, dimension-six operators is computed. The results of this calculation can be use…
Next-to-Leading QCD Corrections to B -> X_s gamma: Standard Model and Two-Higgs Doublet Model
M. Ciuchini, G. Degrassi, P. Gambino +1
We present the QCD corrections to the matching conditions of the Delta B =1 magnetic and chromo-magnetic operators in the Standard Model and in two-Higgs doublet models. We use an…
Charming-penguin enhanced B decays
M. Ciuchini, R. Contino, E. Franco +2
Long-distance contributions of operators of the effective non-leptonic weak Hamiltonian containing charmed currents have been recently studied. Penguin-like contractions of these o…
CP Violating B Decays in the Standard Model and Supersymmetry
M. Ciuchini, E. Franco, G. Martinelli +2
We study the uncertainties of the Standard Model (SM) predictions for CP violating B decays and investigate where and how supersymmetric (SUSY) contributions may be disentangled. T…
Charming Penguins in B decays
M. Ciuchini, E. Franco, G. Martinelli +1
Full expressions of the and amplitudes, given in terms of matrix elements of operators of the effective weak Hamiltonian, are used to study…
: three years later
Marco Ciuchini
Three years after the completion of the next-to-leading order calculation, the status of the theoretical estimates of is reviewed. In spite of the theoretical progress, the…
