报告摘要

In the environment of newly formed black hole, even small amounts of

plasma can support a strong magnetic field up to 10^11 Gauss in a short time, and

also proton could be accelerated to ∼ 10^20 eV. After acceleration, in such extreme

environment, the dominated energy loss process of proton is through their interaction

with the strong magnetic fields, that is, the so-called pB process (Yuan and Shi 2019).

The maximum energy of neutrino produced due to the pB process can reach to ∼ 10 EeV.

In the case of GW150914 detected by Advanced LIGO, the neutrino flux is estimated

to be below the detection limit of IceCube. Neutrinos associating with the merging of

nearby black hole binary with distance 􏰁 5 Mpc could be detected by the current IceCube

detector, and the diffuse neutrino background resulting from black hole mergers could be detected by the future IceCube-Gen2.
