and kaons are likely to be produced in the interactions of shock accelerated relativistic
protons with low energy photons (KeV–MeV). These particles subsequently decay to high
energy neutrinos/antineutrinos and other secondaries. In the high internal magnetic fields of
gamma ray bursts, the ultrahigh energy charged particles (μ+, π+, K+) lose energy
significantly due to synchrotron radiations before decaying into secondary high energy …
