论文摘要
我们介绍了一种新颖的仿射重力模型，该模型实现了无规模的场景。也就是说，普朗克质量和哈勃常数通过自发破坏量表变量的机理动态出现。此外，在我们的模型中，时间方向和非分类度量也动态出现。这自然会导致通货膨胀，并且可能会成为宇宙“出生”的起点。我们表明，从重力和宇宙进化的直接测试的角度来看，我们的模型在现象学上是可行的。
We introduce a novel model of affine gravity, which implements the no-scale scenario. Namely, Planck mass and Hubble constant emerge dynamically, through the mechanism of spontaneous breaking of scale-invariance. Moreover, in our model the time direction and non--degenerate metric emerge dynamically as well. This naturally gives rise to the inflation and may server as a starting point for the "birth" of the Universe. We show that our model is phenomenologically viable, both from the perspective of the direct tests of gravity and cosmological evolution.
