摘要:

本文研究了高维旋转黑洞中标量向体中的辐射。我们获得了一个解析解的场方程采用匹配技术在近地平线和远场制度有效的表达式。在低能和低角动量的限制,吸收概率的解析和数值结果,推导出,并发现是非常一致的。我们还计算了能量发射率,并表明,膜体比的能量发射率的标量场保持始终大于统一在上述制度。

英文摘要:

We study the emission of scalars into the bulk from a higher-dimensional rotating black hole. We obtain an analytic solution to the field equation by employing matching techniques on expressions valid in the near-horizon and far-field regimes. Both analytic and numerical results for the absorption probability, in the low-energy and low-angular momentum limit, are derived and found to be in excellent agreement. We also compute the energy emission rate, and show that the brane-to-bulk ratio of the energy emission rates for scalar fields remains always larger than unity in the aforementioned regime.
