Conformal Invariance, Anomalous Gravitational Coupling and Derivation of a Particle Concept
Hadi Salehi, Yousef Bisabr
We study a gravitational model whose vacuum sector is invariant under conformal transformations. In this model we investigate the anomalous gravitational coupling of the large-scal…

Conformal Anomaly and Large Scale Gravitational Coupling
H. Salehi, Y. Bisabr
We present a model in which the breackdown of conformal symmetry of a quantum stress-tensor due to the trace anomaly is related to a cosmological effect in a gravitational model. T…
