矢量场的霍金辐射与引力异常

Hawking radiation of a vector field and gravitational anomalies

Keiju Murata, Umpei Miyamoto

摘要:

最近,霍金辐射与引力异常之间的关系被用来估计一大类黑色天体的霍金辐射通量。本文将Robinson和Wilczek最初提出的形式推广到矢量粒子(光子)的霍金辐射。它明确表明,与哈密顿形式主义,d维球形黑洞的电磁场的理论减少到一个无限数量的大规模复杂的标量场的2维时空,通常的反常抵消方法是可用的。结果表明,电磁场从视界发射的总能量是标量场的d-2倍。结果支持了霍金辐射可以作为地平异常消除器的观点。可能的扩展和应用的分析进行了讨论。

英文摘要:

Recently, the relation between Hawking radiation and gravitational anomalies has been used to estimate the flux of Hawking radiation for a large class of black objects. In this paper, we extend the formalism, originally proposed by Robinson and Wilczek, to the Hawking radiation of vector particles (photons). It is explicitly shown, with Hamiltonian formalism, that the theory of an electromagnetic field on d-dimensional spherical black holes reduces to one of an infinite number of massive complex scalar fields on 2-dimensional spacetime, for which the usual anomaly-cancellation method is available. It is found that the total energy emitted from the horizon for the electromagnetic field is just (d-2) times as that for a scalar field. The results support the picture that Hawking radiation can be regarded as an anomaly eliminator on horizons. Possible extensions and applications of the analysis are discussed.
