| Research Abstract |
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.
