On quantum gravity of massive gravity

在这项研究中，我们研究了一种给引力子赋予质量的机制，这种机制介导了引力相互作用。在爱因斯坦的广义相对论中，引力子的质量在逐渐消失。然而，超弦理论和宇宙学已经指出，引力子可能具有不消失的质量。我们通过对一般坐标不变性的自发对称破缺，成功地使引力子具有质量。我们的研究在基本粒子物理和宇宙学领域有一定的应用前景。

In this study, we have investigated a mechanism to give a mass to the graviton which mediates the gravitational interaction. In the Einstein’ s general relativity, the graviton has the vanishing mass. However, it has been pointed out by superstring theories and cosmology that the graviton might have the non-vanishing mass. We have succeeded in making the graviton massive via spontaneous symmetry breakdown of general coordinate invariance. Our study would have some applications in elementary particle physics and cosmology in future.
