文摘The collisional Penrose process of massive spinning particles in a rotational Einstein-Gauss-Bonnet(EGB) black hole background is studied. By numerically solving the equations of motion for spinning particles, we find that the energy extraction efficiency increases monotonically with the decrease of the EGB coupling parameterα. Moreover, the efficiency η increases as the particle spin s grows. We also find that the energy extraction efficiency increases with the decrease of the EGB coupling parameter α. When the EGB coupling constant α = 0, our results reduce to the Kerr case, which has been investigated previously.
