Neutrinos from pulsar wind bubbles as precursors to gamma-ray bursts

The supranova model for [Formula presented]-ray bursts (GRBs) has recently gained popularity. In this scenario the GRB occurs weeks to years after a supernova explosion, and is located inside a pulsar wind bubble (PWB). High energy protons from the PWB can interact with photons from the rich radiation field inside the PWB or collide with cold protons from the supernova remnant, producing pions which decay into [Formula presented] neutrinos. The predicted neutrino flux from the PWBs that host the GRBs should be easily detectable by planned [Formula presented] detectors.
