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,…
