In this paper we study the effects of the coupling constant of the Chern–Simons modified gravity on some physical properties of black holes. The Hawking mass is one of the proposed definitions of quasilocal mass. We find that, for slowly rotating Chern–Simons black holes, the Hawking mass is independent of the coupling constant. Next, we show the dependence on the centre of mass energy, for two neutral colliding particles, of coupling constant and the rotation parameter. We also investigate energy extraction through Penrose process and find that the energy gain and efficiency of the Penrose process are independent of this coupling constant. Rotation of the polarization vector is also studied for dependence on the Chern–Simons coupling constant.

在本文中，我们研究了Chern-Simons修正重力的耦合常数对黑洞某些物理性质的影响。霍金质量是拟局部质量的拟议定义之一。我们发现，对于缓慢旋转的Chern-Simons黑洞，霍金质量与耦合常数无关。接下来，我们显示耦合常数和旋转参数对两个中性碰撞粒子的质量能中心的依赖性。我们还研究了Penrose过程的能量提取，发现Penrose过程的能量增益和效率与该耦合常数无关。还研究了偏振矢量的旋转对Chern-Simons耦合常数的依赖性。
