Exploring the R\'enyi Holographic Dark Energy Model with the Future and the Particle Horizons as the Infrared Cut-off

We study the R\'enyi holographic dark energy (RHDE) model by using the future and the particle horizons as the infrared (IR) cut-off. With the initial condition from the literature, most of the cosmological parameters are computed. Some of the results agree with the observation that the present universe is in accelerating expansion and in a phantom phase.
