We propose a scenario that can naturally explain the observed darkmatter-baryon ratio in the context of bimetric theory with a chameleon field.We introduce two additional gravitational degrees of freedom, the massivegraviton and the chameleon field, corresponding to dark matter and dark energy,respectively. The chameleon field is assumed to be non-minimally coupled todark matter, i.e., the massive graviton, through the graviton mass terms. Wefind that the dark matter-baryon ratio is dynamically adjusted to the observedvalue due to the energy transfer by the chameleon field. As a result, the modelcan explain the observed dark matter-baryon ratio independently from theinitial abundance of them.
