AbstractProtons accelerated in the internal shocks of a long-duration gamma-ray burst (GRB) can escape the fireball as cosmic rays by converting to neutrons. Hadronic interactions of these neutrons inside a stellar wind bubble created by the progenitor star will produce TeV gamma-rays via neutral meson decay and synchrotron radiation by charged pion-decay electrons in the wind magnetic field. Such gamma-rays should be observable from nearby GRBs by currently running and upcoming ground-based detectors.
