  • We propose a cosmological scenario involving a single scalar field, $\varphi$, that is a source of Dark Matter as well as Dark Energy. The Lagrangian density of $\varphi$ contains a second field $\chi$, for simplicity assumed to be a scalar. For fixed values of $\chi$, the potential of $\varphi$ decays exponentially at large positive $\varphi$-values. While $\varphi$ is not coupled to Standard Model fields, $\chi$ is assumed to couple to them. Hence, the Green functions of $\chi$ depend on the… CONTINUE READING
