Abstract :
Dust dominated cosmological model has many problems to explain accelerating universe. Many models have been proposed which tells that dark energy causes acceleration of the universe. The evolution of the universe is described by Einstein’s theory of general relativity. This paper examines the possibility of solving problem of accelerating universe by modifying gravity with generalised non-minimally coupled scalar field model. We have generalized the scalar-curvature coupling model of Higgs inflation to . The field equations of a generalized type gravity model, in which there is an arbitrary coupling between matter and geometry, are obtained. The equations of motion for test particles are derived from a variational principle and checked for energy conditions in order to explain acceleration of the universe. The developed dynamics has been studied under different energy conditions which has been implemented in graphs. The presence of scalar-gravity interaction term is not dominated over the first two terms of Klein-Gordon equation showing scalar-gravity interaction is not viable for accelerating universe.
