Stellar-mass black holes (BHs) surrounded by neutrino-dominated accretionflows (NDAFs) are the plausible candidates to power gamma-ray bursts (GRBs) vianeutrinos emission and their annihilation. The progenitors of short-durationGRBs (SGRBs) are generally considered to be compact binaries mergers. Accordingto the simulation results, the disk mass of the NDAF has been limited aftermerger events. We can estimate such disk mass by using the current SGRBobservational data and fireball model. The results show that the disk mass of acertain SGRB mainly depends on its output energy, jet opening angle, andcentral BH characteristics. Even for the extreme BH parameters, some SGRBsrequire massive disks, which approach or exceed the limits in simulations. Wesuggest that there may exist alternative magnetohydrodynamic processes or somemechanisms increasing the neutrino emission to produce SGRBs with thereasonable BH parameters and disk mass.

Can black-hole neutrino-cooled disks power short gamma-ray bursts?
