Direct CP violation in K->3pi decays induced by SUSY chromomagnetic penguins
G. D'Ambrosio, G. Isidori, G. Martinelli
An analysis of the CP violating asymmetry in decays in the Standard Model and, by means of the mass insertion approximation, in a wide class of possible supers…
Renormalization Group Invariant Matrix Elements of DS = 2 and DI = 3/2 Four-Fermion Operators without Quark Masses
A. Donini, V. Gimenez, L. Giusti +1
We introduce a new parameterization of four-fermion operator matrix elements which does not involve quark masses and thus allows a reduction of systematic uncertainties. In order t…
Epsilon'/epsilon from Lattice QCD
M. Ciuchini, E. Franco, L. Giusti +2
Lattice calculations of matrix elements relevant for kaon decays, and in particular for epsilon'/epsilon, are reviewed. The role of the strange quark mass is also discussed. A comp…
Combined analysis of the unitarity triangle and CP violation in the Standard Model
M. Ciuchini, E. Franco, L. Giusti +2
We perform a combined analysis of the unitarity triangle and of the CP violating parameter epsilon'/epsilon using the most recent determination of the relevant experimental data an…
Penguin amplitudes: charming contributions
M. Ciuchini, E. Franco, G. Martinelli +1
We briefly introduce the Wick-contraction parametrization of hadronic matrix elements and discuss some applications to B and K physics.
Weak Matrix Elements without Quark Masses on the Lattice
L. Giusti
We introduce a new parameterization of four-fermion matrix elements which does not involve quark masses and thus allows a reduction of systematic uncertainties in physical amplitud…
