A classical cosmological model for triviality

H. Salehi, P. Moyassari, R. Rashidi

The aim of this paper is to study the triviality of theory in a classical gravitational model. Starting from a conformal invariant scalar tensor theory with a self-interac…

Hawking Radiation in Trace Anomaly Free Frames

H. Salehi, S. Mirabotalebi

We have used the results of renormalization of a two-dimensional quantum stress tensor to develop a conformally invariant dynamical model. The model requires the consideration of t…

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…

Vacuum-Structure and a Relativistic Pilot Wave

Hadi Salehi, Hossein Motavali, Mehdi Golshani

We study a model for analyzing the effect of a principal violation of the Lorentz-invariance on the structure of vacuum. The model is based on the divergence theory developed by Sa…

Conformal invariance and particle aspects in general relativity

H. Salehi, H. R. Sepangi, F. Darabi

We study the breakdown of conformal symmetry in a conformally invariant gravitational model. The symmetry breaking is introduced by defining a preferred conformal frame in terms of…

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…
