Connection between supernova shocks, flavor transformation, and the neutrino signal

TL;DR

This paper discusses how supernova shock waves influence neutrino flavor transformation and how detecting these effects can reveal details about shock dynamics and neutrino properties.

Contribution

It demonstrates that supernova neutrino signals can show signatures of shock propagation affecting flavor transformation, offering new ways to study supernova physics and neutrino parameters.

Findings

Neutrino signals exhibit characteristic signatures during shock propagation.

Detection of these signatures can inform on shock re-generation and propagation.

Observations can provide insights into neutrino mass and mixing matrix.

Abstract

We show that the supernova neutrino signal in terrestrial detectors could give characteristic signatures as the shock propagates through the regions where matter-enhanced neutrino flavor transformation takes place. This effect could allow existing and proposed supernova neutrino detectors to provide new insights into the problem of shock re-generation and propagation. Alternatively, such observations could allow unique insights into the neutrino mass and mixing matrix.
