The consequences of large θ_13 for the turbulence signatures in supernova neutrinos

Abstract

The set of transition probabilities for a single neutrino emitted from a point source after passage through a turbulent supernova density profile have been found to be random variates drawn from parent distributions whose properties depend upon the stage of the explosion, the neutrino energy and mixing parameters, the observed channel, and the properties of the turbulence such as the amplitude C*. In this paper we examine the consequences of the recently measured mixing angle θ_13 upon the neutrino flavor transformation in supernova when passing through turbulence. We find the measurements of a relatively large value of θ_13 means the neutrinos are relatively immune to small, C* < 1%, amplitude turbulence but as C* increases the turbulence effects grow rapidly and spread to all mixing channels. For C* > 10% the turbulence effects in the high (H) density resonance mixing channels are independent of θ_13 but non-resonant mixing channels are more sensitive to turbulence when θ_13 is large.
