Description
Gamma-ray bursts (GRB) were proposed as a leading candidate for the high
energy cosmic ray source and therefore, neutrinos. However, the null
result from the recent search with GRBs by IceCube had challenged this
scenario. Here we revisit both the conventional fireball
shock model and new GRB models, such as a dissipative photospheric model,
baryonic or magnetic models, with a more refined calculation. The result
shows that the current non-detection of GRB neutrinos is in fact not
surprising. With ten years of operation by IceCube and new experiments
covering a even broader energy band, the high energy neutrinos should
be able to tell us the correct GRB model from above, or rule all of them
out.
