We take $f(R,T)$ as $R$ + $8\\pi \\mu T$. As in the $\\Lambda$CDM model, we take the matter to consist of two components, viz., $\\Omega_m$ and $\\Omega_{\\mu}$ such that $\\Omega_m$ + $\\Omega_{\\mu}$=1. The parameter $\\Omega_m$ is the matter density (baryons + dark matter), and $\\Omega_{\\mu}$ is the density associated with the Ricci scalar $R$ and the trace $T$ of the energy momentum tensor, which we shall call dominant matter.
