In this analysis, we assume the validity of cosmic distance duality relation and the flat universe. In order to explore the $\\gamma(z)$ behavior, three different parametrizations are considered, namely: (P1) $\\gamma(z_l)=\\gamma_0+\\gamma_1 z_l$, (P2) $\\gamma(z_l)=\\gamma_0+\\gamma_1 z_l/(1+z_l)$ and (P3)","authors_text":"Deepak Jain, R.
