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 parameter . Moreover, the efficiency increases as the particle spin s grows. We also find that the energy extraction efficiency increases with the decrease of the EGB coupling parameter . When the EGB coupling constant , our results reduce to the Kerr case, which has been investigated previously.

4D旋转Einstein-Gauss-Bonnet黑洞碰撞彭罗斯过程 国家自然科学基金面上项目（11775082）

研究了旋转 Einstein-Gauss-Bonnet (EGB) 黑洞背景中大量自旋粒子的碰撞彭罗斯过程。通过数值求解旋转粒子的运动方程，我们发现能量提取效率随着 EGB 耦合参数的减小而单调增加。此外，效率随着粒子自旋s 的增加而增加。我们还发现能量提取效率随着 EGB 耦合参数的减小而增加。当 EGB 耦合常数为 时，我们的结果减少到之前研究过的 Kerr 情况。
