and the baryon asymmetry of the universe
Carolina Arbeláez, Juan Carlos Helo, Martin Hirsch +1
The observed baryon asymmetry (BAU) of the universe puts strong constraints on any -violating interaction. An observation of a -violating nucleon decay channel would…
Effective Field Theory and Scalar Triplet Dark Matter
Carolina Arbeláez, Marcela González, Martin Hirsch +2
We discuss an extension of the standard model with a real scalar triplet, , including non-renormalizable operators (NROs) up to . If is odd under a symmetry, the…
How many 1-loop neutrino mass models are there?
Carolina Arbeláez, Ricardo Cepedello, Juan Carlos Helo +2
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 questio…
Long-lived charged particles and multi-lepton signatures from neutrino mass models
Carolina Arbeláez R, Giovanna Cottin, Juan Carlos Helo +1
Lepton number violation (LNV) is usually searched for by the LHC collaborations using the same-sign di-lepton plus jet signature. In this paper we discuss multi-lepton signals of L…
Radiative Seesaw-type Mechanism of Fermion Masses and Non-trivial Quark Mixing
Carolina Arbeláez, A. E. Cárcamo Hernández, Sergey Kovalenko +1
We propose a predictive inert 2 Higgs doublet model, where the Standard Model (SM) symmetry is extended by and the field content is enlarged by e…
Fermion dark matter from SO(10)
Carolina Arbelaez, Robinson Longas, Diego Restrepo +1
We construct and analyze nonsupersymmetric SO(10) standard model extensions which explain dark matter (DM) through the fermionic Higgs portal. In these SO(10)-based models the DM p…
Supersymmetric SO(10) GUTs with sliding scales
C. Arbelaez, R. M. Fonseca, M. Hirsch +1
We construct lists of supersymmetric models with extended gauge groups at intermediate steps, all of which are based on SO(10) unification. We consider three different kinds of set…
