A Field Theory Model for Dark Matter and Dark Energy in Interaction

Understand

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.
