1. Beyond R(D(*)) with the general type-III 2HDM for bcτν / Martinez, R. ; Sierra, C. F. ; Valencia, German
We review the parameter regions allowed by measurements of R(D(*)) and by a theoretical limit on B(Bcτν) in terms of generic scalar and pseudoscalar new physics couplings, gs and gp. [...]

2. Charting the flavor landscape of MSSM-like Abelian heterotic orbifolds / Olguín-Trejo, Yessenia ; Pérez-Martínez, Ricardo ; Ramos-Sánchez, Saúl
Discovering a selection principle and the origin of flavor symmetries from an ultraviolet completion of particle physics is an interesting open task. [...]

3. NNLO soft function for top quark pair production at small transverse momentum / Ángeles-Martínez, René ; Czakon, Michał ; Sapeta, Sebastian
The cross section for top quark pair production factorizes at small transverse momentum of the heavy quark pair, q T . [...]

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

5. SM Higgs boson and tcZ 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 tcZ and tch1 from the scalar sector in the two Higgs doublet model type III with CP violation, where h1 is the Standard Model Higgs boson. [...]

6. Fermion mass hierarchy from nonuniversal Abelian extensions of the standard model / Diaz, Carlos E. ; Mantilla, S. F. ; Martinez, R.
A nonuniversal Abelian extension U(1)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). [...]

8. Increase of the energy necessary to probe ultraviolet theories due to the presence of a strong magnetic field / Martínez-y-Romero, Rodolfo ; Patiño, Leonardo ; Ramírez-Urrutia, Tiber
We use the gauge gravity correspondence to study the renormalization group flow of a double trace fermionic operator in a quark-gluon 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.

10. Fermion masses and mixings in the 3-3-1 model with right-handed neutrinos based on the S3 flavor symmetry / Hernández, A. E. Cárcamo ; Martinez, R. ; Ochoa, F.
We propose a 3-3-1 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. [...]
