Natural 2HDMs without FCNCs
J. L. Diaz-Cruz, U. J. Saldana-Salazar, K. M. Tame-Narvaez +1
Motivated by the fermion mass hierarchy we study the phenomenology of two flavorful two-Higgs-doublet model (2HDM) scenarios. By virtue of the flavor or singular alignment ansatz i…
Natural axion model from flavour
Salvador Centelles Chuliá, Christian Döring, Werner Rodejohann +1
We explore a common symmetrical origin for two long standing problems in particle physics: the strong CP and the fermion mass hierarchy problems. The Peccei--Quinn mechanism solves…
Two-Higgs-Doublet Models with a Flavored
S. Centelles Chuliá, W. Rodejohann, U. J. Saldaña-Salazar
Two Higgs-doublet models usually consider an ad-hoc discrete symmetry to avoid flavor changing neutral currents. We consider a new class of two Higgs-doublet models…
Viable low-scale model with Universal and Inverse Seesaw Mechanisms
A. E. Cárcamo Hernández, Juan Marchant González, U. J. Saldaña-Salazar
We formulate a viable low-scale seesaw model, where the masses for the standard model (SM) charged fermions lighter than the top quark emerge from a universal seesaw mechanism medi…
Multi-Higgs-Doublet Models and Singular Alignment
Werner Rodejohann, Ulises Saldaña-Salazar
We consider a 4-Higgs-doublet model in which each Higgs doublet gives mass to one of the fermion sets , , , and . The…
The mass ratios parametrization
Ulises J. Saldana-Salazar, Karla M. Tame-Narvaez
The observed hierarchy in the fermion masses, which imply a set of small mass ratios, is not naturally small regarding 't Hooft's criteria. In this work, in a model independent app…
Texture zeros and hierarchical masses from flavour (mis)alignment
Wolfgang G. Hollik, Ulises J. Saldana-Salazar
We introduce an unconventional interpretation of the fermion mass matrix elements. As the full rotational freedom of the gauge-kinetic terms renders a set of infinite bases called…
Linking LFV Higgs decays with CP violation in multi-scalar models
E. Barradas-Guevara, J. Lorenzo Diaz-Cruz, O. Felix-Beltran +1
The study of LFV decays of the Higgs boson, , has become an active research subject both from the experimental and theoretical points of view. Such decays vanis…
Fermion masses as mixing parameters in the SM
U. J. Saldaña-Salazar
Flavor transitions via the charged current interactions are parametrized by a three dimensional and unitary transformation. This so called mixing matrix requires of four mixing par…
A principle for the Yukawa couplings
U. J. Saldana-Salazar
Yukawa couplings in the Standard Model are introduced in its most general form, that is, completely arbitrary complex numbers. Here we show that their origin could not be general b…
A bottom-up approach to the strong CP problem
J. L. Díaz-Cruz, W. G. Hollik, U. J. Saldaña-Salazar
The strong CP problem is one of many puzzles in the theoretical description of elementary particle physics that still lacks an explanation. While top-down solutions to that problem…
The flavor-blind principle: A symmetrical approach to the Gatto-Sartori-Tonin relation
U. J. Saldaña-Salazar
We perform a systematic study of the generic Gatto-Sartori-Tonin relation, . This study of fermion mixing phenomena leads us to the necessary conditions that…
Higgs couplings and new signals from Flavon-Higgs mixing effects within multi-scalar models
J. Lorenzo Diaz-Cruz, Ulises J. Saldana-Salazar
Testing the properties of the Higgs particle discovered at the LHC and searching for new physics signals, are some of the most important tasks of Particle Physics today. Current me…
