Interacting Energy Components and Observational $H(z)$ Data

Hao Wei Shuang-Nan Zhang

Abstrak

In this Letter, we extend our previous work [H. Wei, S.N. Zhang, Phys. Lett. B 644 (2007) 7, astro-ph/0609597], and compare eleven interacting dark energy models with different couplings to the observational H(z) data. However, none of these models is better than the simplest ACDM model. This implies that either more exotic couplings are needed in the cosmological models with interaction between dark energy and dust matter, or there is no interaction at all. We consider that this result is disadvantageous to the interacting dark energy models studied extensively in the literature. (c) 2007 Elsevier B.V. All rights reserved.
