Phenomenology of the Zee model for Dirac neutrinos and general neutrino interactions
Julián Calle, Diego Restrepo, Óscar Zapata
The Zee model for Dirac neutrinos is one of the simplest models featuring one-loop Dirac neutrino masses. The interactions between the new scalars (two singly-charged fields) and n…
Anomaly-free Abelian gauge symmetries with Dirac scotogenic models
Nicolás Bernal, Julián Calle, Diego Restrepo
We perform a systematic analysis of standard model extensions with an additional anomaly-free gauge symmetry, to generate Dirac neutrino masses at one loop. Under such symme…
Dirac neutrino mass generation from Majorana messenger
Julián Calle, Diego Restrepo, Óscar Zapata
The radiative type-I seesaw has been already implemented to explain the lightness of Majorana neutrinos with both Majorana and Dirac heavy fermions, and the lightness of Dirac neut…
Minimal radiative Dirac neutrino mass models
Julian Calle, Diego Restrepo, Carlos E. Yaguna +1
Neutrinos may be Dirac particles whose masses arise radiatively at one-loop, naturally explaining their small values. In this work we show that all the one-loop realizations of the…
Probing a simplified, model of anomalies using -tags, leptons and missing energy
Mohammad Abdullah, Julian Calle, Bhaskar Dutta +2
We study the LHC sensitivity to a produced via bottom and charm quarks and decaying to flavor leptons in the mass range 200-1000 GeV. We show that the extra quarks nec…
