Quasi-Dirac neutrinos in the linear seesaw model
Carolina Arbeláez, Claudio Dib, Kevin Monsálvez-Pozo +1
We implement a minimal linear seesaw model (LSM) for addressing the Quasi-Dirac (QD) behaviour of heavy neutrinos, focusing on the mass regime of . Here we sh…
anomalies and neutrino mass
Carolina Arbeláez, Ricardo Cepedello, Renato M. Fonseca +1
Motivated by the experimentally observed deviations from standard model predictions, we calculate the anomalous magnetic moments for in a neutrino mass model…
Radiative type-I seesaw neutrino masses
Carolina Arbeláez, A. E. Cárcamo Hernández, Ricardo Cepedello +2
We discuss a radiative type-I seesaw. In these models, the radiative generation of Dirac neutrino masses allows to explain the smallness of the observed neutrino mass scale for rat…
Long-lived heavy particles in neutrino mass models
Carolina Arbeláez, Juan Carlos Helo, Martin Hirsch
All extensions of the standard model that generate Majorana neutrino masses at the electro-weak scale introduce some "heavy" mediators, either fermions and/or scalars, weakly coupl…
Probing the Dirac or Majorana nature of the Heavy Neutrinos in pure leptonic decays at the LHC
Carolina Arbelaéz, Claudio Dib, Iván Schmidt +1
We propose a strategy for distinguishing the Dirac / Majorana character of heavy neutrinos with masses below the boson mass, using purely leptonic decays at the LHC. The strate…
QCD-improved limits from neutrinoless double beta decay
Carolina Arbeláez, Marcela González, Sergey Kovalenko +1
We analyze the impact of QCD corrections on limits derived from neutrinoless double beta decay (). As demonstrated previously, the effect of the color-mismatch arising from l…
QCD Corrections and Long-Range Mechanisms of neutrinoless double beta decay
Carolina Arbeláez, Marcela González, Martin Hirsch +1
Recently it has been demonstrated that QCD corrections are numerically important for short-range mechanisms (SRM) of neutrinoless double beta decay () mediated by heavy parti…
Adjoint GUT model with flavor symmetry
Carolina Arbeláez, A. E. Cárcamo Hernández, Sergey Kovalenko +1
We propose an adjoint GUT model with a family symmetry and an extra discrete group, that succ…
LHC-scale left-right symmetry and unification
Carolina Arbeláez, Martin Hirsch, Michal Malinský +1
We construct a comprehensive list of non-supersymmetric standard model extensions with a low-scale LR-symmetric intermediate stage that may be obtained as simple low-energy effecti…
Witten's mechanism in the flipped SU(5) unification
Carolina Arbeláez, Helena Kolešová, Michal Malinský
We argue that the Witten's loop mechanism for the right-handed Majorana neutrino mass generation identified originally in the SO(10) grand unification context can be successfully a…
