Confronting Tracker Field Quintessence with Data

Pao-Yu Wang, Chien-Wen Chen, Pisin Chen

We confront tracker field quintessence with observational data. The potentials considered in this paper include $V(\varphi )\propto {\varphi }^{-\alpha }$, $\exp (M_p/\varphi )$, $\exp (M_p/\varphi )-1$, $\exp(βM_{p…
