Cardenas, Victor H.Lepe, Samuel2021-08-262021-08-262020http://repositoriobibliotecas.uv.cl/handle/uvscl/2276We 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 Λ CDM model without assuming an exotic dark energy.enDARK ENERGYDARK MATTERCOSMOLOGYArticulohttps://doi.org/10.1140/epjc/s10052-020-08443-4
