论文摘要

我讨论了如何应用Vilkovisky和DeWitt开发的协方差形式主义,以获得标量调节理论的框架不变的第五力量计算。第五力受到天体物理测量的严重限制。先前显示的是,对于刻度不变的希格斯 - 迪拉顿重力,在约旦框架的特殊选择中,dilaton第五力被极大地抑制,从而逃避了观察性约束。使用几何方法,我将此结果扩展到所有框架,并表明“约旦框架”与“爱因斯坦框架”的常规二分法更好地理解为框架的连续体:更一般的田间空间的子序列切片。

I discuss how one can apply the covariant formalism developed by Vilkovisky and DeWitt to obtain frame invariant fifth force calculations for scalar-tensor theories. Fifth forces are severely constrained by astrophysical measurements. It was shown previously that for scale-invariant Higgs-dilaton gravity, in a particular choice of Jordan frame, the dilaton fifth force is dramatically suppressed, evading the observational constraints. Using a geometric approach I extend this result to all frames, and show that the usual dichotomy of "Jordan frame" versus "Einstein frame" is better understood as a continuum of frames: submanifold slices of a more general field space.
