Probing the inverted mass ordering region and venturing into the normal mass ordering region of neutrinos is a crucial goal for the next generation of neutrinoless double beta decay (0νββ) experiments. The absence of definitive signatures, the quest for heightened sensitivity, background minimization, statistical significance, and exploration of multiple isotopes collectively drive the move...
Scenario with a lepton-flavor-violating (LFV) boson, either a scalar or a vector exchange, is an intriguing physics phenomenon beyond Standard Model. This LFV boson coupling in the presence of muons leads to a rich phenomenology including an extra contribution to muon anomalous magnetic moment desirable for alleviating the discrepancy between the SM prediction and the newest combined (Fermilab...
Based predominantly on arXiv: 2012.07519 (JCAP 03 (2021) 084) and also on arXiv: 2207.07142 (JCAP 10 (2022) 018).
We have updated the constraints on flavour universal (and also flavour specific) neutrino self-interactions mediated by a heavy scalar, in the effective 4-fermion interaction limit. We use the relaxation time approximation to modify the collisional neutrino Boltzmann equations,...
In this talk we will discuss the phenomenology of neutrino mass models where leptoquarks mediate the generation of Dirac mass terms. The presence of leptoquarks that couple to all generations of quarks and leptons can have interesting consequences for meson decays. In particular the RD,RD*anomalies can be addressed, as well as the recent observation by Belle-II of an excess in the B-> K + inv...
Recent measurement of muon anomalous magnetic dipole moment (muon $g-2$), performed by the Muon $g-2$ Collaboration at Fermilab, differs from the Standard Model (SM) value calculated by the Muon $g-2$ Theory Initiative Group at the combined statistical significance of $5.1\sigma$. Taking at face value, such discrepancy could be an indication of some sort of new physics. In this paper, we...
Motivated by a hint of possible excess of a new resonance decaying to eμ at 146 GeV, we try to interpret the excess in the context of the type-III two-Higgs-doublet-model. We find that the excess is only moderately constrained by low-energy lepton-flavor-violation processes, in particular the μ→eγ decay. We also compare the CMS bounds across the entire search region against constraints of μ→eγ...
When a core-collapse supernova fails to explode or barely exploded, i.e., unable to unbind most of the stellar envelope, the associated proto-neutron star is expected to eventually implode into a black hole. In this scenario, the neutrino luminosity spectrum will then see an abrupt end as a result of the engulfment of the luminous core and the increasing gravitational redshift. The dynamics...
