引力场Anomaly中黑p膜的霍金辐射

Hawking Radiation of Black p-Branes from Gravitational Anomaly

Zheng Ze Ma

摘要:

本文用反常消去方法研究了超弦理论中的黑$p$ -膜的霍金辐射,特别是用[S. Iso,H. Umetsu和F. Wilczek,{ \sl Phys. Rev. Lett.} { \bf 96},151302(2006); { \sl Phys. Rev. D} { \bf 74},044017(2006)]。黑$p$ -膜的度规是球对称的,但不是史瓦西型的。为了简化计算,我们首先进行坐标变换,将度规变换为史瓦西型。然后利用上述文献中的异常消去法计算了它的能量动量通量。得到的能量动量通量等于一个黑体辐射,辐射的热力学温度等于其Hawking温度。我们发现,对于原来的非Schwarzschild型球对称度规,结果并没有改变。

英文摘要:

We investigate the Hawking radiation of black $p$-branes of superstring theories using the method of anomaly cancelation, specially, we use the method of [S. Iso, H. Umetsu and F. Wilczek, {\sl Phys. Rev. Lett.} {\bf 96}, 151302 (2006); {\sl Phys. Rev. D} {\bf 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 transformation to transform the metric to the Schwarzschild type. Then we calculate its energy-momentum flux from the method of anomaly cancelation of the above mentioned references. The obtained energy-momentum flux is equal to a black body 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.
