In this work, for the first time the implementation of the 3-3-1 model with right-handed neutrinos without exotic electric charges in SARAH package of MATHEMATICA is presented, and it shows how it correctly reproduces the analytical results of the model. As proof of this, we present the mass matrices for the quark sectors, where a Higgs sector with three scalar triplets has been used. Then,...
It is presented a non-universal $U(1)_{X}$ extension to the Standard Model with two scalar doublets, two scalar singlets, three additional quark singlets, two lepton singlets and three generations of right-handed and Majorana neutrinos is made to explain lepton mass hierarchy and muon anomalous magnetic moment in a chiral anomaly free framework. Besides, neutrino mass generation is achieved by...
The three-loop corrections to the Higgs boson mass are usually computed in the on-shell scheme using the effective potential approach, where the external momentum are put equal to zero. In this presentation we are going to discuss the technical details for the Feynman diagrammatic computation of the external momentum dependence coming from the three-loop self-energy corrections to the Higgs...
This contribution explores the Machine Learning techniques and Quantum Computing concepts and applications in High Energy Physics considering a phenomenological and theoretical view. Besides, we show the main tools to explore the Standard Model extensions, decay process and the parameter space. With this set of tools, we want to explore the bounds and define exclusion regions, those bounds...
In this talk I will present our recent advances in the calculation of scattering amplitudes using strong homotopy algebras. This prescription inspired from string field theory allows to construct a generating function for all the tree-level scattering amplitudes. Several examples will be presented.
In this work, we consider a non-quadratic dilaton $\Phi(z)=(\kappa\,z)^{2-\alpha}$ in the context of the static soft wall model to describe the mass spectrum of a wide range of vector mesons from the light up to the heavy sectors. The effect of this non-quadratic approach is translated into non-linear Regge trajectories with the generic form $M^2=a\,(n+b)^\nu$. We apply this sort of fits for...
We show that in the presence of the torsion tensor $S^k_{\phantom{k}ij}$, the quantum commutation relation for the four-momentum, traced over spinor indices, is given by $[p_i,p_j]=2i\hbar S^k_{\phantom{k}ij}p_k$.
In the Einstein--Cartan theory of gravity, in which torsion is coupled to spin of fermions, this relation in a coordinate frame reduces to a commutation relation of noncommutative...
Theories with anisotropy between space and time, also called Horava-Lifshtiz (HL) theories, has been studied in many works since the seminal paper of P. Horava was published, where the Lifshitz scaling is used to construct a power counting renormalizable gravity model. The Lifshitz scaling is described by the transformation $x\rightarrow bx$, $t\rightarrow b^zt$, where the integer $z$ is...
