摘要
我们提出了一种在扭转-尺度场存在下的新型自洽最小耦合原理。该原理产生一种新的局部尺度不变性,并预测扭转-尺度场与真实物质以及度规之间的相互作用。该对称性的软失效导致实际的尺度场,并在该新模型的引力场中给出卡尔半标量曲率与宇宙常数的简单关系。我们讨论了其与标量-张量引力理论的关系,以及扭转-尺度场在气动学情景中的可能应用。\noindent{PACS 号:04.50.+h, 04.40.Nr, 04.62.+v}

备注
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
