讨论了高维Schwarzschild黑洞的引力子吸收几率（灰体因子）和截面。我们的动机的建议，大量的黑洞可能会产生在大型强子对撞机和铭记这一事实，为简单起见，我们将调查的中间能源制度的静态史瓦西黑洞。即对于（2 M）1/（n？（1）？~ 1，其中M是黑洞的质量，？是在（2+n）维中发射的引力子的能量。为了找到容易处理的解，我们在l >> 1的极限下工作，其中l是引力子的角动量量子数。
We discuss the graviton absorption probability (greybody factor) and the cross-section of a higher-dimensional Schwarzschild black hole (BH). We are motivated by the suggestion that a great many BHs may be produced at the LHC and bearing this fact in mind, for simplicity, we shall investigate the intermediate energy regime for a static Schwarzschild BH. That is, for (2M)1/(n?1)? ~ 1, where M is the mass of the black hole and ? is the energy of the emitted gravitons in (2+n)-dimensions. To find easily tractable solutions we work in the limit l >> 1, where l is the angular momentum quantum number of the graviton.
