摘要
The Penrose process of an extremal braneworld black hole is studied. We analyze the Penrose process by two massive spinning particles colliding near the horizon. By calculating the maximum energy extraction efficiency of this process, it turns out that the maximal efficiency increases as the tidal charge parameter d of the braneworld blackhole decreases. Interestingly, for the negative value of d, the efficiency can be even larger than the Kerr case.
