Reconstruction of hessence dark energy and the latest type Ia supernovae gold dataset
Recently, many efforts have been made to build dark energy models whose equation-of-state parameter can cross the so-called phantom divide ${w}_{\mathrm{de}}=\ensuremath{-}1$. One of them is the so-called hessence dark energy model in which the role of dark energy is played by a noncanonical complex scalar field. In this work, we …
