Title: Probing the Origins of Neutrino Mass with Supernova Data

Abstract

We study type II supernova signatures of neutrino mass generation via symmetry breaking at a scale in the range from keV to MeV. The scalar responsible for symmetry breaking is thermalized in the supernova core and restores the symmetry. The neutrinos from scalar decays have about half the average energy of thermal neutrinos. The Bose-Einstein distribution of the scalars can be established with a megaton water Cerenkov detector. The discovery of the bimodal neutrino flux is, however, well within the reach of the Super-Kamiokande detector, without a detailed knowledge of the supernova parameters.

  • We investigate the feasibility of probing the neutrino mass hierarchy and the mixing angle {phi}{sub 13} with the neutrino burst from a future supernova. An inverse power-law density {rho}{approx}r{sup n} with varying n is adopted in the analysis as the density profile of a typical core-collapse supernova. The survival probabilities of {nu}{sub e} and {nu}{sub e} are shown to reduce to two-dimensional functions of n and {phi}{sub 13}. It is found that in the n-sin{sup 2}{phi}{sub 13} parameter space, the 3D plots of the probability functions exhibit highly nontrivial structures that are sensitive to the mass hierarchy, the mixing anglemore » {phi}{sub 13}, and the value of n. The conditions that lead to observable differences in the 3D plots are established. With the uncertainty of n considered, a qualitative analysis of the Earth matter effect is also included.« less

  • The neutrino mass hierarchy is one of the neutrino fundamental properties yet to be determined. We introduce a method to determine neutrino mass hierarchy by comparing the interaction rate of neutral current (NC) interactions, ν(ν-bar)+p→ν(ν-bar)+p, and inverse beta decays (IBD), ν-bar{sub e}+p→n+e{sup +}, of supernova neutrinos in scintillation detectors. Neutrino flavor conversions inside the supernova are sensitive to neutrino mass hierarchy. Due to Mikheyev-Smirnov-Wolfenstein effects, the full swapping of ν-bar{sub e} flux with the ν-bar{sub x} (x=μ, τ) one occurs in the inverted hierarchy, while such a swapping does not occur in the normal hierarchy. As a result, more highmore » energy IBD events occur in the detector for the inverted hierarchy than the high energy IBD events in the normal hierarchy. By comparing IBD interaction rate with the mass hierarchy independent NC interaction rate, one can determine the neutrino mass hierarchy.« less
  • We analyze the possibility of probing nonstandard neutrino interactions (NSI, for short) through the detection of neutrinos produced in a future galactic supernova (SN). We consider the effect of NSI on the neutrino propagation through the SN envelope within a three-neutrino framework, paying special attention to the inclusion of NSI-induced resonant conversions, which may take place in the most deleptonized inner layers. We study the possibility of detecting NSI effects in a Megaton water Cherenkov detector, either through modulation effects in the {nu}{sub e} spectrum due to (i) the passage of shock waves through the SN envelope, (ii) the timemore » dependence of the electron fraction, and (iii) the Earth matter effects; or, finally, through the possible detectability of the neutronization {nu}{sub e} burst. We find that the {nu}{sub e} spectrum can exhibit dramatic features due to the internal NSI-induced resonant conversion. This occurs for nonuniversal NSI strengths of a few %, and for very small flavor-changing NSI above a fewx10{sup -5}.« less
  • Supernovae of Type II is a phenomenon that occurs at the end of the evolution of massive stars when the iron core of the star exceeds a mass limit. After the collapse of the core under gravity the shockwave alone does not succeed in expelling the mass of the star and in this sense the role of neutrinos is the most important mechanism to do so. During the emission of neutrinos flavor conversion is possible, related the phenomenon of oscillations, which however depends directly on the particular density profile of the medium. In this paper we present results of numericalmore » simulations of neutrino flavor conversion in supernovae after bounce. The probabilities of survival for a given flavor in a complete three-flavors framework is estimated through an algorithm which conserves unitarity to a high degree of accuracy. The sensitivity of the results to the different adopted models for the supernova structure is examined in detail demonstrating how the neutrino signal could be used to check the validity of models.« less
