| Abstract | A component of dark energy has been recently proposed to explain the current acceleration of the Universe. Unless some unknown symmetry in Nature prevents or suppresses it, such a field may interact with the pressureless component of dark matter, giving rise to the so-called models of coupled quintessence. In this paper we propose a new cosmological scenario where radiation and baryons are conserved, while the dark energy component is decaying into cold dark matter (CDM). The dilution of CDM particles, attenuated with respect to the usual a−3 scaling due to the interacting process, is characterized by a positive parameter ǫ, whereas the dark energy satisfies the equation of state px = ùñx (ù < 0). We carry out a joint statistical analysis involving recent observations from type Ia supernovae, baryon acoustic oscillation peak, and Cosmic Microwave ackground shift parameter to check the observational viability of the coupled quintessence scenario here proposed. |
