Observational Constraints on Varying Alpha in $\Lambda (\alpha )$CDM Cosmology

Hao Wei, Dong-Ze Xue

In this work, we consider the so-called $\Lambda (\alpha )$CDM cosmology with $\Lambda \propto {\alpha }^{-6}$ while the fine-structure "constant" $\alpha$ is varying. In this scenario, the accelerated expansion of…
