摘要：

In this paper, we have constructed Re ' nyi Holographic Dark Energy (RHDE) in Ruban's Universe within the framework of Saez-Ballester scalar tensor theory (Saez and Ballester, Phys. Lett.A 113, 467 1986), where the IR cutoff is taken care by the Hubble horizon. The field equations are solved by considering the relationship between the metric potentials of the model. To examine the evolutionary dynamics of the model, we obtain cosmological implications such as Hubble parameter, deceleration parameter, equation of state parameter (omega(de)), omega(de,) omega'(de) code plane, square speed of sound (v(s)(2) ) and Om-diagnostic parameter. It is also quite interesting to mention here that the results of equation of state parameter (omega(de)) and omega(de) - omega'(de) plane coincide with the modern observational data.
