Abstract:In this paper, we have constructed the cosmological model of the universe in f(RT) theory of gravity in a Bianchi type (mathrm{VI}_h) universe for the functional f(RT) in the form (f(R,T)=mu R+mu T), where R and T are respectively Ricci scalar and trace of energy momentum tensor and (mu ) is a constant. We have made use of the hyperbolic scale factor to find the physical parameters and metric potentials defined in the space-time. The physical parameters are constrained from different representative values to build up a realistic cosmological model aligned with the observational behaviour. The state finder diagnostic pair is found to be in the acceptable range. The energy conditions of the model are also studied.
