A Field Theory Model for Dark Matter and Dark Energy in Interaction
arXiv:0902.0318 · doi:10.1103/PhysRevD.79.123506
Abstract
We propose a field theory model for dark energy and dark matter in interaction. Comparing the classical solutions of the field equations with the observations of the CMB shift parameter, BAO, lookback time and Gold supernovae sample, we observe a possible interaction between dark sectors with energy decay from dark energy into dark matter. The observed interaction provides an alleviation to the coincidence problem.
