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

Understand

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.
