Revisiting observational constraints on coupled exponential quintessence with energy and momentum transfers: degeneracy with massive neutrinos

Jose Beltrán Jiménez, Kiyotomo Ichiki, Xiaolin Liu +2

We investigate the impact of massive neutrinos on cosmological models in which dark energy, described by a quintessence scalar field $\ddot{I}•$ with an exponential potential, interacts w…
