Effects of time-varying $\beta$ in SNLS3 on constraining interacting dark energy models

Shuang Wang, Yong-Zhen Wang, Jia-Jia Geng +1

It has been found that, for the Supernova Legacy Survey three-year (SNLS3) data, there is strong evidence for the redshift-evolution of color-luminosity parameter $\beta$. In this pape…
