Latest Observational Constraints to the Ghost Dark Energy Model by Using Markov Chain Monte Carlo Approach
Chao-Jun Feng, Xin-Zhou Li, Xian-Yong Shen
Recently, the vacuum energy of the QCD ghost in a time-dependent background is proposed as a kind of dark energy candidate to explain the acceleration of the universe. In this mode…
