We demonstrate that the rotating four-dimensional Gauss– Bonnet black hole can act as a particle accelerator with arbitrarily high centre-of-mass (CM) energy, when collision of two general particles takes place near the event horizon. The particles are at rest initially at infinity, and by fine tuning their angular momenta within a finite range, they are released so that they follow the time-like geodesics in the black hole spacetime, and the collision taking place on the equatorial plane is observed. The Gauss–Bonnet coupling constant $\alpha$, provides a deviation in the results, from that observed in the Kerr black hole. The horizon structure, the range of allowed angular momentum and the critical angular momentum depend on the value of $\alpha$. Our results show that the CM energy depends on the coupling parameter $\alpha$ in addition to the black hole spin $a$. For extremal cases, the CM energy diverges at the horizon, suggesting that Gauss–Bonnet black hole can also act as a particle accelerator similar to a Kerr black hole. For the non-extremal case, there exists a finite upper bound on the CM energy, the maximal value of which depends on the parameter $\alpha$.

我们证明，当两个一般粒子在事件视界附近发生碰撞时，旋转的四维 Gauss-Bonnet 黑洞可以充当具有任意高质心 (CM) 能量的粒子加速器。粒子最初在无穷远处静止，通过在有限范围内微调它们的角动量，它们被释放，以便它们遵循黑洞时空中的类时测地线，并观察到赤道平面上发生的碰撞. Gauss-Bonnet 耦合常数$\alpha$，提供了与在克尔黑洞中观察到的结果的偏差。视界结构、允许角动量范围和临界角动量取决于$\alpha$. 我们的结果表明 CM 能量取决于耦合参数$\alpha$ 除了黑洞自旋 $\mathrm{一种}$. 对于极端情况，CM 能量在视界发散，这表明 Gauss-Bonnet 黑洞也可以充当类似于 Kerr 黑洞的粒子加速器。对于非极值情况，CM 能量存在一个有限的上限，其最大值取决于参数 $\alpha$.
