Open AccessThree-loop inverse scotogenic seesaw models
We propose a class of models providing an explanation of the origin of light neutrino masses, the baryon asymmetry of the Universe via leptogenesis and offering viable dark matter candidates. In these models t...

Open AccessFermion mass hierarchy in an extended left-right symmetric model
We present a Left-Right symmetric model that provides an explanation for the mass hierarchy of the charged fermions within the framework of the Standard Model. This explanation is achieved through the utilizat...

Open AccessPhenomenological and cosmological implications of a scotogenic three-loop neutrino mass model
We propose a scotogenic model for generating neutrino masses through a three-loop seesaw. It is a minimally extended inert doublet model with a spontaneously broken global symmetry U(1)′ and a preserved ℤ2 symmet...

Open AccessHow many 1-loop neutrino mass models are there?
It is well-known that at tree-level the d = 5 Weinberg operator can be generated in exactly three different ways, the famous seesaw models. In this paper we study the related question of how many phenomenological...

Open AccessRGE effects on the LFV scale from meson decays
We consider the lepton-flavor violating (LFV) lepton-quark dimension-6 operators and analyze their contributions to the LFV leptonic decays of vector, pseudoscalar, and scalar neutral mesons

Open AccessScotogenic neutrino masses with gauged matter parity and gauge coupling unification
Building up on previous work we propose a Dark Matter (DM) model with gauged matter parity and dynamical gauge coupling unification, driven by the same physics responsible for scotogenic neutrino mass generati...

An extended 3-3-1 model with two scalar triplets and linear seesaw mechanism
Low energy linear seesaw mechanism responsible for the generation of the tiny active neutrino masses is implemented in the extended 3-3-1 model with two scalar triplets and right-handed Majorana neutrinos wher...

Open AccessFermion mass hierarchy and g − 2 anomalies in an extended 3HDM Model
We propose an extension of the three-Higgs-doublet model (3HDM), where the Standard Model (SM) particle content is enlarged by the inclusion of two inert SU2L scalar doublets, three inert and two active electrica...

Open AccessSequentially loop suppressed fermion masses from a single discrete symmetry
We propose a systematic and renormalizable sequential loop suppression mechanism to generate the hierarchy of the Standard Model fermion masses from one discrete symmetry. The discrete symmetry is sequentially...

Open AccessLepton flavor violation and collider searches in a type I + II seesaw model
Neutrinos are massless in the Standard Model. The most popular mechanism to generate neutrino masses are the type I and type II seesaw, where right-handed neutrinos and a scalar triplet are augmented to the St...

Open AccessSequentially loop-generated quark and lepton mass hierarchies in an extended Inert Higgs Doublet model
Extended scalar and fermion sectors offer new opportunities for generating the observed strong hierarchies in the fermion mass and mixing patterns of the Standard Model (SM). In this work, we elaborate on the ...

Open AccessNeutrino predictions from a left-right symmetric flavored extension of the standard model
We propose a left-right symmetric electroweak extension of the Standard Model based on the Δ (27) family symmetry. The masses of all electrically charged Standard Model fermions lighter than the top quark are ...

Open AccessFermion masses and mixings and dark matter constraints in a model with radiative seesaw mechanism
We formulate a predictive model of fermion masses and mixings based on a Δ(27) family symmetry. In the quark sector the model leads to the viable mixing inspired texture where the Cabibbo angle comes from the ...

Open AccessTargeted sequencing reveals complex, phenotype-correlated genotypes in cystic fibrosis
Cystic fibrosis (CF) is one of the most common life-threatening genetic disorders. Around 2000 variants in the CFTR gene have been identified, with some proportion known to be pathogenic and 300 disease-causin...
