The NASA sponsored balloon-borne ANITA detector operating in Antarctica is designed to detect ultra high energy cosmic rays (UHECR) with energies exceeding 1 EeV ($10^{18}$ eV) by collecting the radio pulse generated through the interaction of the primary particle with Earth’s atmosphere. The radio pulse is detected after reflection from the Antarctic ice surface. For calibration and...

Non-Standard Interactions (NSI) of neutrinos with matter are important to understand, as they could significantly alter the standard 3-neutrino oscillation paradigm. While vector NSI contribute as a change in the matter potential for the propagating neutrinos, scalar NSI show up as a correction to the neutrino mass matrix. In this talk, we will discuss the field-theoretic origin of scalar NSI...

Models of radiative Majorana neutrino masses require new scalars and/or fermions to induce lepton number violating interactions. We show that these new particles also generate observable neutrino nonstandard interactions (NSI) with the matter. We classify radiative models as type-I or II, with type-I models containing at least one Standard Model (SM) particle inside the loop diagram generating...

We propose a new way to probe non-standard interactions (NSI) of neutrinos with matter using the ultra-high energy (UHE) neutrino data at current and future neutrino telescopes. We consider the Zee model of radiative neutrino mass generation as a prototype, which allows two charged scalars -- one $SU(2)_L$-doublet and one a singlet, both being leptophilic, to be as light as 100 GeV, thereby...

We carry out a systematic investigation of the minimal Dirac neutrino mass models emerging from generic one-loop and two-loop topologies that arise from $d=5$ effective operator with a singlet scalar, $\sigma$. To ensure that the tree-level Dirac mass, as well as Majorana mass terms at all order are absent for the neutrinos, we work in the framework where the Standard Model is supplemented by...
