Query: Dynamical CP Violation and Flavour-Changing Processes   We investigate the phenomenological constraints on a model where, besides the
standard model Higgs sector, there is an effective new strong interaction
acting on the third generation of quarks and characterized by a $\theta$-like
term. This $\theta$ term induces electroweak symmetry breaking and leads to
dynamical spontaneous CP violation. We show that the constraints coming from K
physics and the electric dipole moment of the neutron impose that the new
physics scale should be of the order of 35 TeV. Contrary to naive expectations,
the predictions of the model for B physics are very close to the standard model
ones. The main differences appear in processes involving the up quarks such as
$D^0-\bar{D}^0$ mixing and in the electric dipole moment of the neutron, which
should be close to the experimental limit. Possible deviations from the
standard model predictions for CP asymmetries in B decays are also considered.
