论文摘要
本文探讨了Braneworld Kerr Black Hole的中性粒子运动和碰撞的Penrose过程。我们分析事件范围，巨石和静态极限的特性。研究了通过Penrose过程中的粒子碰撞。此外，我们研究了负能量，并表明粒子能的迹象可以由角动量的符号独特地确定。此外，我们研究了WALD不等式，以确定通过Penrose工艺提取能量的限制，并找到不可约合质量的下限。发现了从Brane Kerr黑洞中提取能量的效率的表达。最后，我们将结果与从Kerr黑洞获得的结果进行了比较。可以得出结论，效率随旋转的增加以及黑洞的勃雷参数B的增加而提高。
This paper explores the neutral particle motion and collisional Penrose process in ergoregion of the braneworld Kerr black hole. We analyze the properties of event horizon, ergosphere and static limit. The particle collision in ergoregion via the Penrose process is investigated. Furthermore, we study the negative energy states and show that the sign of particle energy can be uniquely determined by the sign of angular momentum. In addition, we study the Wald inequality to determine the limits of energy extraction via the Penrose process and also find lower bound of the irreducible mass. The expression for the efficiency of energy extraction from the brane Kerr black hole is found. Finally, we compare our results with that obtained from the Kerr black hole. It is concluded that efficiency increases with the increase of rotation as well as brane parameter b of the black hole.
