How sensitive to FCNC can CP asymmetries be?
G. Barenboim, F. J. Botella, G. C. Branco +1
We show that the study of CP asymmetries in neutral B-meson decays provides a very sensitive probe of flavour-changing neutral currents (FCNC). We introduce two new angles, $α_{SM}…

Effective Lagrangian in theories with vector like fermions
G. Barenboim, F. J. Botella
In this work we analyze a new piece present in the effective Lagrangian in models with extra vector-like quarks. This piece, which was not taken into account previously, i…

D^0-D^0(bar) mixing in the weak-gauged U(4)_L x U(4)_R Chiral Lagrangian Model
G. Amoros, F. J. Botella, S. Noguera +1
The D^0-D^0(bar) mixing is analyzed in a weak gauged U(4)_L x U(4)_R chiral lagrangian model where the electroweak interaction is introduced as a gauge theory over the meson degree…
