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…
