摘要：

The bulk Lorentz factor of the gamma-ray burst (GRB) ejecta (Gamma(0)) is a key parameter to understanding GRB physics. Liang et al. have discovered a correlation between Gamma(0) and isotropic gamma-ray energy: Gamma(0) alpha E-gamma,iso,52(0.25). By including more GRBs with updated data and more methods to derive Gamma(0), we confirm this correlation and obtain Gamma(0) similar or equal to 91E(gamma,iso,52)(0.29). Evaluating the mean isotropic gamma-ray luminosities L-gamma,L-iso of the GRBs in the same sample, we discover an even tighter correlation Gamma(0) similar or equal to 249L(gamma,iso,52)(0.30). We propose an interpretation to this later correlation. Invoking a neutrino-cooled hyperaccretion disk around a stellar mass black hole as the central engine of GRBs, we derive jet luminosity powered by neutrino annihilation and baryon loading from a neutrino-driven wind. Applying beaming correction, we finally derive Gamma(0) alpha (0.22)(gamma,iso), which is consistent with the data. This suggests that the central engine of long GRBs is likely a stellar mass black hole surrounded by a hyper-accreting disk.
