The top quark is the heaviest elementary particle known, thus it has a wide range of decay modes. Studying this fermion phenomenology it could be possible to explore New Physics (NP) effects. If we onsider the Standard Model (SM) Strong and Electro-Weak interactions, Flavor Changing mediated by Neutral Currents (FCNC) do not exist at tree level and such processes just can success at one loop level

In this work, we use the Lienard-Wiechert electromagnetic field equations to calculate the magnetic field event by event in heavy ion collisions and to find a relationship between the magnetic field created with the impact parameter in the collision. We then implement our results using a Monte-Carlo Glauber model of heavy ion collisions to simulate Au-Au collisions relevant for the Multi Purpose D

The fundamental description of nature, beyond the Standard Model (SM), may include heavy neutrinos that mix and thus allow processes in which lepton flavor is not preserved. We investigate the impact of charged currents that couple heavy gauge bosons to heavy neutrinos and SM leptons on neutrinoless lepton-flavor-violating decays of SM leptons into three charged leptons. We implement our expressio

In this work we study the annihilation of dark matter, considering it as a neutral particle with magnetic and$/$or electric moments not null.

We present the calculation of the cross section for the associated production process of the Higgs boson with a pair of top quark, $pp\to t\bar{t}H$ at different centre-of-mass energies to compare with recent measurements at LHC. Using CalcHEP at leading order calculations we found a good a aproximation in comparison with other values calculated to higher order presented in the literature

Magnetic fields are present in compact objects affecting its structure. The anisotropy produced by the magnetic field in the pressures suggests the necessity of using structure equations considering the axial symmetry of the magnetized system.

In this work we have studied the top quark decay $t\rightarrow c\gamma$ mediated by a neutral gauge boson $V$ which produces flavour changing couplings at tree level. Such a boson can be induced in some theories beyond the Standard Model with an extended gauge group. $t\rightarrow c\gamma$ decay is induced by one loop and the amplitude is generated by three Feynman diagrams in the unitary norm: tw

We perform an effective field theory analysis of the L -> l' X (gamma) decays, where L=tau, mu; l'=mu,e and X is an unknown particle with spin 0 or 1 and with either parity, which mediates LFV processes.

We study the dark matter stability due to the existence of an additional U(1) gauge symmetry. Furthermore, we generate neutrino masses at the radiative level via an effective dimension five Weinberg operator. The presence of an extra Abelian symmetry allows accommodating the recent LHCb anomalies in B → K(K∗)μ+μ− decays,by fixing some parameters of the model.

Precise flavor observable measurements are an indirect and powerful evidence of Physics Beyond the Standard Model (BSM). Flavor observables are sensitive to high energy scales and to direct searches of new particles. A very important observable can be the partial decay reason, which can be studied in four important groups: leptonic and semileptic decays at tree level, rare purely leptonic decays,

A study of the flavor changing decays $t \to cV$ $(V = \gamma,Z)$ and $t\to cH$ is presented in the framework of a minimal scalar leptoquark model in which the standard model is augmented with a single scalar leptoquark doublet with $SU(3)_c\times SU(2)_L\times U(1)_Y$ quantum numbers $(3,2,7/6)$. This model predicts a non-chiral charge $5/3e$ leptoquark coupling to up quarks, and a chiral charge

We consider Dark Matter-SM interactions mediated by spin-one fields, in a general EFT framework.
