论文摘要
在本文中，我们研究了浸入渐近均匀统一磁场的4-D爱因斯坦 - 高斯黑洞附近的磁化颗粒的动力学。我们已经表明，负责圆形轨道的磁相互作用参数降低了高斯参数$α$的负值以及允许磁化粒子稳定的圆形轨道的范围增加了参数$α$的正值。对磁化，充电和中性颗粒的碰撞的研究表明，在存在正高斯河网参数的存在下，颗粒的质量能量增加。最后，我们展示了磁相互作用和高斯河网参数如何模仿Kerr黑洞旋转的影响，从而为磁性颗粒提供了相同的ISCO半径。对ISCO的详细分析表明，当$α<-4.37 $和旋转参数$ a> 0.237 $时，磁相互作用和高斯河网参数的影响无法模仿Kerr黑洞的自旋。
In this paper, we have investigated the dynamics of magnetized particles around 4-D Einstein-Gauss-Bonnet black hole immersed in an external asymptotically uniform magnetic field. We have shown that the magnetic interaction parameter responsible for circular orbits decreases for negative values of the Gauss-Bonnet parameter $α$ and the range where magnetized particle's stable circular orbits are allowed increases for the positive values of the parameter $α$. The study of the collisions of magnetized, charged and neutral particles has shown that the center-of-mass energy of the particles increases in the presence of positive Gauss-Bonnet parameter. Finally, we show how the magnetic interaction and Gauss-Bonnet parameter may mimic the effect of rotation of the Kerr black hole giving the same ISCO radius for magnetized particles. Detailed analysis of the ISCO show that spin of Kerr black hole can not be mimicked by the effects of magnetic interaction and the Gauss-Bonnet parameters when $α<-4.37$ and the spin parameter $a > 0.237$.
