Neutrinos from newborn pulsar winds hitting supernova ejecta could be detected from a galactic source by IceCube if B/P^2 exceeds ~0.003, with parameter constraints and a detectable diffuse flux for next-generation telescopes.

abstract
The origin of the IceCube neutrinos is still an open question. Upper limits from diffuse gamma-ray observations suggest that the neutrino sources are either distant or hidden from gamma-ray observations. It is possible that the neutrinos are produced in jets that are formed in the core-collapsing massive stars and fail to break out, the so-called choked jets. We study neutrinos from the jets choked in the hydrogen envelopes of red supergiant stars. Fast photo-meson cooling softens the neutrino spectrum, making it difficult to explain the PeV neutrinos observed by IceCube in a one-component scenario, but a two-component model can explain the spectrum. Furthermore, we predict that a newly born jet-driven type-II supernova may be observed to be associated with a neutrino burst detected by IceCube.

Exploring the properties of newborn pulsars with high-energy neutrinos
Neutrinos from newborn pulsar winds hitting supernova ejecta could be detected from a galactic source by IceCube if B/P^2 exceeds ~0.003, with parameter constraints and a detectable diffuse flux for next-generation telescopes.
