Beyond $R\left({D}^{(*)}\right)$ with the general typeIII 2HDM for $b\to c\tau \nu $
/ Martinez, R. ; Sierra, C. F. ; Valencia, German
We review the parameter regions allowed by measurements of $R\left({D}^{(*)}\right)$ and by a theoretical limit on $B({B}_{c}\to \tau \nu )$ in terms of generic scalar and pseudoscalar new physics couplings, ${g}_{s}$ and ${g}_{p}$. [...]

$B$ meson decay anomaly with a nonuniversal $U(1{)}^{\prime}$ extension
/ Martinez, R. ; Ochoa, F. ; Quimbayo, J. M.
We propose an extension of the standard model with an extra $U(1{)}^{\prime}$ Abelian symmetry, three Higgs doublets and two Higgs singlets, where the new $U(1{)}^{\prime}$ charges are flavor nonuniversal. [...]

SM Higgs boson and $t\to cZ$ decays in the 2HDM type III with $CP$ violation
/ Martinez, R. ; Gaitán, R. ; Montes de Oca, J. H. ; Garcés, E. A.
We compute the contributions to rare top decays $t\to cZ$ and $t\to c{h}_{1}$ from the scalar sector in the two Higgs doublet model type III with $CP$ violation, where ${h}_{1}$ is the Standard Model Higgs boson. [...]

Fermion mass hierarchy from nonuniversal Abelian extensions of the standard model
/ Diaz, Carlos E. ; Mantilla, S. F. ; Martinez, R.
A nonuniversal Abelian extension ${U\left(1\right)}_{X}$ free from chiral anomalies is introduced into the standard model (SM), in order to evaluate its suitability in addressing the fermion mass hierarchy (FMH) by using seesaw mechanisms (SSM). [...]

Increase of the energy necessary to probe ultraviolet theories due to the presence of a strong magnetic field
/ MartínezyRomero, Rodolfo ; Patiño, Leonardo ; RamírezUrrutia, Tiber
We use the gauge gravity correspondence to study the renormalization group flow of a double trace fermionic operator in a quarkgluon plasma subject to the influence of a strong magnetic field and compare it with the results for the case at zero temperature and no magnetic field, where the flow between two fixed points is observed.

Fermion masses and mixings in the 331 model with righthanded neutrinos based on the S3 flavor symmetry

We propose a 331 model where the SU(3)C⊗SU(3)L⊗U(1)X symmetry is extended by S3⊗Z3⊗Z3′⊗Z8⊗Z16 and the scalar spectrum is enlarged by extra SU(3)L singlet scalar fields. [...]
