We study the effective hamiltonian for the atomic parity violation for the weak interactions. The contribution of new physics is taken into account. [ABSTRACT FROM AUTHOR]

We consider the contribution of the charged Higgs boson for the meson decay process with bottom quark in two leptons, B± → l± vl, we find the region allowed for the mass of the charged Higgs and the parameters of flavor changing, in the SM and 2DHM type III. [ABSTRACT FROM AUTHOR]

We study restrictions on the vertices in the quark sector of the two Higgs doublet model type III, using the value measured for ΔMBd ; taking into account the Cheng-Sher parameterization, and considering a very heavy charged Higgs boson. [ABSTRACT FROM AUTHOR]

The top quark mass (~174 GeV) is of the same order of the electroweak symmetry breaking scale which suggests that the top quark must be more sensitive to the new physics than the remaining fermions. In this work the Chromo-Magnetic Dipole Moment (CMDM) of the top quark is calculated in the context of the Standard Model. The prediction is ΔkSM = -5,6 x 10-2 at one loop order.

Neutral Higgs boson production with b quarks in the final state increases in Two Higgs Doublets Models type II and III. We study the light Higgs and b quark production for four and five flavors schemes at TEVATRON, using the 2HDM with a large value for tan(β). By adjusting the values obtained in simulations to experimental results coming from TEVATRON, we find validity ranges for some couplings in the Chen, Sher and Yuang ansatz, with which we calculate the cross section for the process pp → bb̄h(bb̄) in the LHC collider for 2HDM type III.

In the framework of the models based on the gauge symmetry SU(3)C x SU(3)L x U(1)X including supersymmetry without any exotic charges asigned to the fermionic spectrum, we obtain neutrino masses when we diagonalize the neutralino mass matrix. We get the allowed region of parameters which agree with the experiments of neutrino oscillations. [ABSTRACT FROM AUTHOR]

We consider one family version of the 331 models and study the unification with two symmetry breaking. [ABSTRACT FROM AUTHOR]

An interesting extension of the Standard Model is based on the electroweak gauge group SU(3)L ⊗ U(1). We have calculated the mass matrices for different models. Models one family and three families which do not contain particles with exotic electric charges are presented. [ABSTRACT FROM AUTHOR]
