Behaviour of Bianchi Type-V Dark Energy Model in f(R,T) Gravity with a Specific Form of Hubble Parameter

Abstract

Abstract: In this paper, we have constructed a Bianchi type V cosmological model, in the presence of bulk viscous fluid and within the framework of f(R,T) theory of gravity with an appropriate choice of the functional f(R,T)in the form f(R,T )=R+2f(T), where R and T are respectively Ricci scalar and trace of energy momentum tensor. In order to obtain a deterministic solution, we have considered two general forms of hyperbolic scale factors. The different forms of scale factors considered here produce time-varying deceleration parameters in all the cases that simulate the cosmic transition. The state finder diagnostic pair is found to be in the acceptable range. The physical parameters are constrained from different representative values to build up a realistic cosmological model aligned with the observational behaviour.
