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

Understand

In this note, we extend our previous work [Phys.

• Lett.
• B 644, 7 (2007), 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 $\Lambda$CDM model.
