We poropose an extension of the hypothesis of Minimal
Flavour Violation to two Higgs doublet Models without
the assumption of Natural Flavour Conservation in the
Higgs sector. The potentially dangerous flavour changing
neutral currents are suppressed by small entries of the
CKM matrix as a result of a discrete symmetry imposed to
the Lagrangian. This discrete symmetry is also...

Higgs Physics at LHC and Beyond
Contribution (25 + 5 min)
According to the usual analysis, if the Standard Model (SM) is
valid up to the Planck scale $M_P$, the stability condition of
the electroweak (EW) vacuum (stable, metastable or unstable)
mainly depends on the Higgs and top masses, $M_H$ and $M_t$.
The analysis is performed by considering SM interactions only,
as it is argued that new physics at $M_P$, although present,
has no...

The Higgs sector with more than one Higgs doublet may have de\-ge\-ne\-ra\-cy in its physical states.
Considering also $CP$ symmetry is not conserved in the Higgs sector, then the neutral Higgs states would not have a defined $CP$ charge,{\it i.e.} there is a mixing within scalar and pseudoscalar components of the Higgs doublets. This situation will occur for the cMSSM, {\it i.e.} with...

We present an overview of the flavour groups S3 and Q6 in models with an extended Higgs sector. We extend the S3 results to SU(5) Grand Unified theories with Q6 as flavour group. We find the generic form of the mass matrices both in the quark and lepton sectors, which are consistent with experimental data. We reproduce, according to current data, the mixing in the CKM matrix. In the leptonic...
