TeV neutrinos from core collapse supernovae and hypernovae

Abstract

A fraction of core collapse supernovae of type Ib/c are associated with Gamma-ray bursts, which are thought to produce highly relativistic jets. Recently, it has been hypothesized that a larger fraction of core collapse supernovae produce slower jets, which may contribute to the disruption and ejection of the supernova envelope, and explain the unusually energetic hypernovae. We explore the TeV neutrino signatures expected from such slower jets, and calculate the expected detection rates with upcoming Gigaton Cherenkov experiments. We conclude that individual jetted SNe may be detectable from nearby galaxies.Comment: 4 pages 2 figures. Modified from the published version. Errors in Eqs. 2, 3, 5 are corrected and predicted neutrino event rates are modified accordingly. The conclusions for the diffuse flux remain unchanged, and those for individual nearby sources are strengthene
