Cosmic acceleration and phantom crossing in -gravity
In this paper, we propose two new models in gravity to realize
universe acceleration and phantom crossing due to dark torsion in the
formalism. The model parameters are constrained and the observational test are
discussed. The best fit results favors an accelerating universe with possible
phantom crossing in the near past or future followed respectively by matter and
radiation dominated era.Comment: 20 pages, 18 figures, Will appear in Astrophys Space Sc
