摘要：

We will focus on the effect of a Weyl-invariant model with a quadratic interaction term and a free scalar field psi. A set of analytic solutions will be obtained for this model. This model provides a dynamical alternative to the standard Lambda CDM model. In particular, we will show that the quartic Weyl-invariant model prediction is consistent with the Hubble diagram observations.
