QCD ghost f(T)-gravity model    [PDF]

K. Karami, A. Abdolmaleki
We reconstruct a f(T) modified teleparallel gravity model corresponding to
the ghost dark energy scenario. We calculate the effective torsion equation of
state and deceleration parameters of the ghost f(T)-gravity model. We conclude
that the equation of state parameter behaves like a freezing quintessence
model. Furthermore, the deceleration parameter can justify the transition from
the cosmic deceleration to acceleration phase of the universe. Also the present
value of the deceleration parameter is in good agreement with the recent
observations.
