Searching for Sterile Neutrinos with Total Energy Momentum Reconstruction
, 2020 The first part of the thesis is a recalculation of supernova bounds on neutrino radiative decays. Specifically, we will be looking at supernova 1987A (SN 1987A).

Second leptogenesis: Unraveling the baryon-lepton asymmetry discrepancy
Journal of High Energy PhysicsWe propose a novel scenario to explain the matter-antimatter asymmetry by twofold leptogenesis, wherein heavy Majorana neutrinos exhibit temperature-dependent masses and engage in CP-violating decays.

Testable inverse seesaw motivated from a high quality QCD axion
Journal of High Energy PhysicsThe QCD axion remains one of the most compelling solutions to the strong CP problem. Meanwhile, the type-I seesaw mechanism offers an elegant explanation for the lightness of the observed neutrino masses; however, its extremely heavy Majorana states ...

First bounds on effective muon interactions using the NA64μ experiment at CERN
Journal of High Energy PhysicsWe analyze how NA64μ can contribute to the global SMEFT program demonstrating that it can probe two effective four-lepton operators completely unbounded so far and break one of the current flat directions. Furthermore, we also study an extension of SMEFT

Space–time evolution of heavy sterile neutrinos in cascade decays
, 2014 Heavy sterile-like neutrinos may be produced resonantly from the decay of pseudoscalar mesons and may decay into several different channels in a cascade Φ→Lανh; νh→{X}. In general these are rare events with displaced vertices.

Electromagnetic leptogenesis with light-heavy sterile neutrinos
We propose a novel leptogenesis scenario utilising the two-body decay of heavy right handed neutrino (RHN) via the electromagnetic dipole operator. While the requirement of the standard model (SM) gauge invariance requires such dipole operator only at ...
