Neutrinoless Double-Beta Decays from Operator Mixing

J. de Vries, S. Fajfer, L. P. S. Leal +2

We perform a complete one-loop Renormalization Group (RG) analysis of neutrinoless double-beta decays within the Standard Model Effective Field Theory (SMEFT). Although several eff…

New Avenues for = 2 Processes Beyond Neutron-Antineutron Oscillations

Arnau Bas i Beneito, Svjetlana Fajfer, Alexey A. Petrov

We explore baryon-number-violating () processes beyond the well-known neutron-antineutron () oscillations, focusing on the system. The presenc…

Neutrino Mass Induced - Oscillation

Ilja Dorsner, Svjetlana Fajfer, Shaikh Saad

The Georgi-Glashow model is the simplest possible attempt at grand unification. However, due to its particle content, the model preserves a global symmetry, where

Weak Triplet Models of Neutrino Magnetic Moments

Svjetlana Fajfer, Shaikh Saad

Experimental limits on neutrino magnetic moments remain several orders of magnitude above the predictions of the Standard Model; therefore, any future detection would provide unamb…

Impact of new invisible particles on observables

Patrick D. Bolton, Svjetlana Fajfer, Jernej F. Kamenik +1

Motivated by a recent Belle~II measurement that suggests an excess in the rare decay , and building upon our recent differential decay rate likelihood analy…

Beyond Neutrino Mass: Observable - Oscillations in UV Complete Seesaw Models

Ilja Dorsner, Svjetlana Fajfer, Shaikh Saad

Next-generation experiments, such as the Deep Underground Neutrino Experiment and the European Spallation Source, are set to improve sensitivity to neutron-antineutron oscillation,…
