Abstract

We have developed an accelerating cosmological model for the present universe which is phantom for the period (0z1.99) (0 \leq z \leq 1.99) and quintessence phase for (1.99z2.0315)(1.99 \leq z \leq 2.0315). The universe is assumed to be filled with barotropic and dark energy(DE) perfect fluid in which DE interact with matter. For a deceleration parameter(DP) having decelerating-accelerating transition phase of universe, we assume hybrid expansion law for scale factor. The transition red shift for the model is obtained as zt=0.956z_t = 0.956. The model satisfies current observational constraints.
