Minimal Model of Dilatonic Gravity and Cosmological Constant

Abstract

We consider: minimal scalar-tensor model of gravity with Brans-Dicke factor $\omega (\Phi )\equiv 0$ and cosmological factor $\Pi (\Phi )$; restrictions on it from gravitational experiments; qualitative analysis of new approach to cosmological constant problem based on the huge amount of action in Universe; determination of $\Pi (\Phi )$ using time evolution of scale factor of Universe.
