TeV尺度引力理论允许以即将在欧洲核子研究中心大型强子对撞机或俄歇天文台探索的能量产生小黑洞。预计的特征之一是探测到霍金辐射，如果黑洞一旦受到扰动，离开黑洞膜，这种辐射可能最终会终止。在这里，我们研究了一旦黑洞被赋予一个模拟引力子发射的反冲的初始速度，“黑洞+膜”系统是如何演化的。我们的动力学分析结果表明，膜围绕黑洞弯曲，这表明一旦膜的两部分接触并重新连接，黑洞最终会逃脱到额外的维度。这为婴儿膜的形成提供了一种动力机制。
TeV-scale gravity theories allow the possibility of producing small black holes at energies that soon will be explored at the CERN LHC or at the Auger observatory. One of the expected signatures is the detection of Hawking radiation that might eventually terminate if the black hole, once perturbed, leaves the brane. Here, we study how the "black hole plus brane" system evolves once the black hole is given an initial velocity that mimics, for instance, the recoil due to the emission of a graviton. The results of our dynamical analysis show that the brane bends around the black hole, suggesting that the black hole eventually escapes into the extra dimensions once two portions of the brane come in contact and reconnect. This gives a dynamical mechanism for the creation of baby branes.
