8. Confronting Neutrino Mass Generation Mechanism with MiniBooNE Anomaly

SUDIP JANA (OKLAHOMA STATE UNIVERSITY)

We present a novel framework that provides an explanation to the long-standing excess of electron-like events in the MiniBooNE experiment at Fermilab. We suggest a new dark sector containing a dark neutrino and a dark gauge boson, both with masses between a few tens and a few hundreds of MeV. Dark neutrinos are produced via neutrino-nucleus scattering, followed by their decay to the dark gauge...

42. CP violation in coherent elastic neutrino-nucleus scattering experiments

The presence of new neutrino-quark interactions can enhance, deplete or distort the coherent elastic neutrino-nucleus scattering (CEvNS) event rate. The new interactions can involve CP violating phases that can potentially affect these features. Assuming vector light mediators we study the effects of CP violation on the CEvNS process, and for that aim we consider the COHERENT sodium-iodine...

44. Radiative Dirac neutrino masses

Prof. Diego Alejandro Restrepo Quintero

The realization of the effective operator for generation of genuine radiative Dirac neutrino masses requieres at least one spontaneously symmetry broken extension of the standard model with a singlet scalar. We explore the phenomenology of the minimal realizations of this scenario.
