Interacting dark matter and cosmic acceleration

Abstract

We study the effect of an explicit interaction between two scalar fields components describing dark matter in the context of a recent proposal framework for interaction. We find that, even assuming a very small coupling, it is sufficient to explain the observational effects of a cosmological constant, and also overcome the problems of the $\Lambda$CDM model without assuming an exotic dark energy.
