Abstract
We propose a novel self consistent minimal coupling principle in presence of torsion dilaton field. This principle yields a new local dilatation symmetry and predicts the interactions of torsion dilaton with the real matter and with metric. The soft violation of this symmetry yields a physical dilaton and a simple relation between Cartan scalar curvature and cosmological constant in this new model of gravity with propagating torsion. Its relation with scalar-tensor theories of gravity and a possible use of torsion dilaton in the inflation scenario is discussed. \noindent{PACS number(s): 04.50.+h, 04.40.Nr, 04.62.+v}
Comment: 10 pages, revtex, no figures. The discovered misprints are corrected, new references, acknowledgments, and Appendix are added. Substantial changes in formulas and results are made in sections 4 and 5 where a new cosmological potential for torsion dilaton is introduced. In addition the relation of our model of gravity with propagating torsion with scalar-tensor theories of gravity and a possible use of torsion dilaton in the inflation scenario are discussed
