We explore the possibility of probing the nonstandard interactions between the neutrino and a hypothetical massive scalar or pseudoscalar via neutrino flavor transformation in supernovae. We find that in ultrarelativistic limit, the effective interaction between the neutrinos does not vanish if neutrinos are Majorana fermions but does vanish if neutrinos are Dirac fermions. The impact of the new neutrino interaction upon the flavor transformation above the neutrinosphere has been calculated in… 

Exploring the effects of scalar non standard interactions on the CP violation sensitivity at DUNE

The Neutrino oscillations have provided an excellent opportunity to study new-physics beyond the Standard Model, popularly known as BSM. The unknown couplings involving neutrinos, termed non-standard

Probing non-standard neutrino interactions with a light boson from next galactic and diffuse supernova neutrinos

Abstract Non-standard neutrino interactions with a massive boson can produce the bosons in the core of core-collapse supernovae (SNe). After the emission of the bosons from the SN core, their

Non-Standard Neutrino Self-Interactions Can Cause Neutrino Flavor Equipartition Inside the Supernova Core

We show that non-standard neutrino self-interactions can lead to total flavor equipartition in a dense neutrino gas, such as those expected in core-collapse supernovae. In this first investigation of

Scalar Nonstandard Interactions in Neutrino Oscillation.

A synergy of different types of experiments, especially those with matter density variation, is necessary to identify the scalar NSI and guarantee the measurement of CP violation at accelerator experiments.

Searching for BSM neutrino interactions in dark matter detectors

Neutrino interactions beyond the Standard Model (BSM) are theoretically well motivated and have an important impact on the future precision measurement of neutrino oscillation. In this work, we study

Imprints of scalar NSI on the CP-violation sensitivity using synergy among DUNE, T2HK and T2HKK

The Non-Standard Interactions (NSIs) are subdominant effects, often appearing in various extensions of SM, which may impact the neutrino oscillations through matter. It is important and interesting

Fast Flavor Depolarization of Supernova Neutrinos.

A theory of fast flavor depolarization is presented, explaining how neutrino flavor differences become smaller, i.e., depolarize, due to diffusion to smaller angular scales, and it is shown that transverse relaxation determines the epoch of this irreversibledepolarization.



Nonstandard Neutrino Interactions in Supernovae

Nonstandard interactions (NSI) of neutrinos with matter can significantly alter neutrino flavor evolution in supernovae with the potential to impact explosion dynamics, nucleosynthesis, and the

Nonstandard neutrino self-interactions in a supernova and fast flavor conversions

We study the effects of non-standard self-interactions (NSSI) of neutrinos streaming out of a core-collapse supernova. We show that with NSSI, the standard linear stability analysis gives rise to

We investigate the effects of nonstandard four-fermion neutrino-neutrino interactions on the flavor evolution of dense neutrino gases. We find that in the regions where the neutrino-neutrino

No collective neutrino flavor conversions during the supernova accretion phase.

It is found that the multiangle effects associated with the dense ordinary matter suppress collective oscillations of the supernova (SN) neutrino flavor evolution during the accretion phase, and the possible detection of the next galactic SN neutrinos signal from the accrete phase can reveal the neutrini mass hierarchy.
