TeV-PeV Neutrinos from Low-Power Gamma-Ray Burst Jets inside Stars

Understand

We study high-energy neutrino production in collimated jets inside progenitors of gamma-ray bursts (GRBs) and supernovae, considering both collimation and internal shocks.

• We obtain simple, useful constraints, using the often overlooked point that shock acceleration of particles is ineffective at radiation-mediated shocks.
• Classical GRBs may be too powerful to produce high-energy neutrinos inside stars, which is consistent with IceCube nondetections.
• We find that ultralong GRBs avoid such constraints and detecting the TeV signal will support giant progenitors.
