Relaxing the Cosmological Constraints on Unparticle Dark Component

Understand

Unparticle physics has been an active field since the seminal work of Georgi.

• Recently, many constraints on unparticles from various observations have been considered in the literature.
• In particular, the cosmological constraints on the unparticle dark component put it in a serious situation.
• In this work, we try to find a way out of this serious situation, by including the possible interaction between dark energy and the unparticle dark component.
