  Minimal Theory of Fermion Masses   We present a detailed study of Delta F=2 observables and of rare K^+(K_L) and
B_{s,d} meson decays in a "Minimal Theory of Fermion Masses" (MTFM). In this
theory Yukawa couplings are generated through the mixing with heavy vectorlike
(VF) fermions. This implies corrections to the SM quark couplings to W, Z and
Higgs so that FCNC processes receive contributions from tree level Z and Higgs
exchanges and W bosons couple to right-handed quarks. In a particular version
of this model in which the Yukawa matrix lambda^D in the heavy down fermion
sector is unitary, lambda^U =1 and M = M_{VF} is fixed, only three real and
positive definite parameters describe New Physics (NP) contributions to all
Delta F=2 and Delta F=1 observables in K and B_{s,d} systems once the known
quark masses and the CKM matrix are correctly reproduced. For M>1 TeV NP
contributions to B_{s,d}^0- bar{B}_{s,d}^0 mixings are found to be very small.
While in principle NP contributions to epsilon_K and Delta F=1 processes could
be large, the correlation between epsilon_K and K_L->mu^+ mu^- eliminates
basically NP contributions to epsilon_K and right-handed current contributions
to Delta F=1 FCNC observables. We find CMFV structure in B_{s,d} decays with
BR(B_{s,d}->mu^+ mu^-) uniquely enhanced for M=3 TeV by at least 35% and almost
up to a factor of two over their SM values. Also BR(K^+->pi^+ bar{nu} nu) and
BR(K_L->pi^0 bar{nu} nu)$ are uniquely enhanced by similar amount but the
correlation between them differs from the CMFV one. We emphasize various
correlations between K and B_{s,d} decays that could test this scenario. The
model favours gamma=68{\deg}, |V_{ub}|=0.0037, S_{psi K_S}=0.72, S_{psi
phi}=0.04 and 4.2*10^-9<BR(B_s->mu^+ mu^-)<5.0*10^-9 for M=3-4 TeV.
