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…
Type I + II Seesaw Model in light of the New Neutrino Oscillation Measurements
Maria Aguilar, Juan Carlos Helo, Toshihiko Ota +3
Global analysis of neutrino oscillation data slightly favors normal mass ordering. In this work, we investigate an extended scalar sector that naturally gives rise to a type I + II…
New parameter region in sterile neutrino searches: a scenario to alleviate cosmological neutrino mass bound and its testability at oscillation experiments
Toshihiko Ota
Recent high-precision cosmological data tighten the bound to neutrino masses and start rising a tension to the results of lab-experiment measurements, which may hint new physics in…
Long-range contributions to double beta decay revisited
J. C. Helo, M. Hirsch, T. Ota
We discuss the systematic decomposition of all dimension-7 (d=7) lepton number violating operators. These d=7 operators produce momentum enhanced contributions to the long-range pa…
Double beta decay and neutrino mass models
J. C. Helo, M. Hirsch, T. Ota +1
Neutrinoless double beta decay allows to constrain lepton number violating extensions of the standard model. If neutrinos are Majorana particles, the mass mechanism will always con…
