Scalar-Tensor Theories and Quantum Gravity
Fatimah Shojai, Ali Shojai, Mehdi Golshani
Abstract
Recently, it was shown that the quantum effects of the matter, could be used to determine the conformal degree of freedom of the space-time metric. So both gravity and quantum are geometrical features. Gravity determines the causal structure of the space-time, while quantum determines the scale of the space-time. In this article, it is shown that it is possible to use the scalar-tensor framework to build a unified theory in which both quantum and gravitational effects are present.
