A study of the strength of the lepton flavor-violating $Z^{\prime}\mu\tau$ coupling is presented. We used the experimental value of the muon magnetic dipole moment to bound this coupling, in a model-independent way, represented for the $\Omega_{\mu\tau}$ parameter and it is found that $\Omega_{\mu\tau}\sim 10^{-2}$ for a $Z^\prime$ boson mass of 1 TeV.

The experimental observation of lepton number violating (LNV) processes, where the total lepton number is violated by two units (\Delta L = 2), represents the most appropriate way to address the question of the nature of neutrinos as Majorana or Dirac particles. LNV processes mediated by the exchange of heavy Majorana neutrinos, such as three-body decays of tau lepton and charged pseudoscalar meso

A renormalizable fermion mass model based in the $Q_4$ symmetry is presented. This include both quark and lepton sector and reproduce allowed experimental values for masses and mixing angles. In order to get this result is required to introduce four SU(2) doublet scalar fields transforming non trivially under the flavor symmetry, and as right-handed neutrinos are not present in the model, two ad

The versions of the Two Higgs Doublets Model (2HDM) suppress the Flavour Changing Neutral Currents (FCNC) through different mechanisms as; imposing symmetries on the Higgs doublets or explicitly introducing the
mass hierarchy in the entrances of the Yukawa matrices. Every possibility that nullify FCNC in
the context of the 2HDM generates a new version of this model, but the version that use text

The most theoretically accepted mechanism for the EW symmetry breaking is the Higgs mechanism.
This mechanism has been partially proven through the well measured gauge boson masses. Nevertheless, there is one degree of freedom (in the Standard Model) that still have to
be measured experimentally: the Higgs particle, a scalar boson. Supersymmetric models predicts multiple Higgs particle as residu

We report an updated measurement of the CP-violating phase, $\phi_s^{J/\psi
\phi}$, and the decay-width difference for the two mass eigenstates, $\Delta
\Gamma_s$, from the flavor-tagged decay $B_s^0 \rightarrow J/\psi \phi$. The
data sample corresponds to an integrated luminosity of 8.0 fb$^{-1}$
accumulated with the D0 detector using $p \overline p$ collisions at $\sqrt{s}
= 1.96$ TeV produ

I will briefly present a new derivation of the most general form of the Higgs potential in the framework of the Minimal S3-Invariant Extension of the Standard Model (MS3IESM). By introducing in the theory three Higgs fields that are SU(2) doublets and a permutational symmetry, S3, the concepts of flavours and generations are extended to the Higgs sector. In this work, we will try to clarify som

We discuss the formulation of the Two-Higgs doublet model type III, which
incorporates flavor changing neutral scalar interactions (FCNSI) and CP
violation (CPV) from several sources. CP violation can arise either from
Yukawa terms or from the Higgs potential, be it explicit or spontaneous. We
discuss the limit that includes CPV and Yukawa four textures to control
FCNSI and evaluate the CPV a

Single top quark production at the International Linear Collider (ILC) can be used to obtain
high precision measurements of the Vtb CKM element as well as the effective tbW coupling.
The single top production processes at lepton and photon (e+ e-, e- e-, e gamma and gamma gamma)
colliders have been extensively studied at tree level. The reaction e gamma, is particularly suitable
for precision

We analyze the neutrino electron scattering off electrons and obtain constraints on tensorial couplings. We have studied the non standard interactions formalism as well as the unparticle stuff case. For our analysis we have focused on the recent TEXONO collaboration results. We have obtained new constraints to possible tensorial couplings in both new physics formalisms.

Within the Standard Model of particle physics (SM), particles decay in a way that conserves lepton flavor numbers. Muons then may decay as follow: $mu^{-}to e^{-} nu_{mu}bar{nu}_{e}$, plus radiative corrections. In many scenarios of physics beyond the Standard Model (BSM), there are additional decay modes, such as $mu^{-}to e^{-}gamma$ and $mu^{-}to e^{-} e^{+}e^{-}$, that violate the lepton flavo

Flavour physics in the LHC era has the very ambitious goal to unravel the
intimate structure of Beyond Standard Model physics that is likely to be
dicovered at the LHC. It has also a great potential to search for new
physics beyond the LHC scale. This program requires a very high luminsoity
e+e- collider running principally at the Y(4S) region. SUch a project ,
SuperB, has been recent

Several topics about this decay are reviewed: its importance, its reduction to the
corresponding factors and their calculation. Experimental information and CPV are
analyzed too.

In this talk, I will review some results on masses, mixings and flavour changing neutral currents (FCNC's) of leptons and quarks previously derived in the framework of a minimal S(3)-invariant extension of the Standard Model. Explicit, analytical expressions for the Yukawa matrices of leptons and quarks reparametrized in terms of the corresponding physical masses will be given. I will also give t
