One-loop correction effects on supernova neutrino fluxes: a new possible probe for Beyond Standard Models

TL;DR

This paper investigates how large radiative corrections from Supersymmetry can significantly alter supernova electron neutrino fluxes, offering a potential new way to probe Beyond Standard Model physics through neutrino observations.

Contribution

It demonstrates that SUSY-induced radiative corrections can impact supernova neutrino fluxes and suggests these effects could be used to constrain SUSY parameters.

Findings

Sizable effects on neutrino fluxes may be observable on Earth.

Potential to use neutrino flux measurements to probe BSM physics.

Implications for constraints on SUSY parameter space.

Abstract

We present the consequences of a large radiative correction term coming from Supersymmetry (SUSY) upon the electron neutrino fluxes streaming off a core- collapse supernova using a 3-flavor neutrino-neutrino interaction code. We explore the interplay between the neutrino-neutrino interaction and the effects of the resonance associated with the mu-tau neutrino index of refraction. We find that sizeable effects may be visible in the flux on Earth and, consequently, on the number of events upon the energy signal of electron neutrinos in a liquid argon detector. Such effect could lead to a probe for Beyond Standard Model (BSM) physics and, ideally, to constraints in the SUSY parameter space.
