Interacting modified holographic Ricci dark energy model and statefinder diagnosis in flat universe
Abstract
In this work we have considered the modified holographic Ricci dark energy interacting with dark matter through a non-gravitational coupling. We took three phenomenological forms for the interaction term in the model, where in general is proportional to the Hubble parameter and densities of the dark sectors, and respectively. We have obtained analytical solutions for the three interacting models, and studied the evolutions of equations of state parameter, deceleration parameter. The results are compared with the observationally constrained values for the best parameters of the model. We have also done the statefinder analysis of the model to discriminate the model from other standard models. In general we have shown that the model is showing a de Sitter type behavior in the far future of the evolution of the universe.
