摘要
We investigate the Hawking radiation of black p-branes of superstring theories using the method of anomaly cancellation, specially, we use the method of S. Iso, H. Umetsu and F. Wilczek, Phys. Rev. Lett. 96, 151302 (2006) and Phys. D 74, 044017 (2006). The metrics of black p-branes are spherically symmetric, but not the Schwarzschild-type. In order to simplify the calculation, we first make a coordinate its energy-momentum flux from the method of anomaly cancellation of the above-mentioned references. The obtained energy-momentum flux is equal to a blackbody radiation, the thermodynamic temperature of the radiation is equal to its Hawking temperature. And we find that the results are not changed for the original non-Schwarzschild-type spherically symmetric metric.
