In this work we explore a Holographic Dark Energy Model in a flat Friedmann-LemaÎtre-Robertson-Walker Universe, which contains baryons, radiation, cold dark matter and dark energy within the framework of General Relativity. Furthermore, we consider three types of phenomenological interactions in the dark sector. With the proposed model we obtained the algebraic expressions for the cosmological parameters of our interest: the deceleration and coincidence parameters. Likewise, we graphically compare the proposed model with the ΛCDM model.

En este trabajo exploramos un modelo de energía oscura holográfica en un universo plano de Friedmann-Lemaître-Robertson-Walker, que contiene bariones, radiación, materia oscura fría y energía oscura en
el marco de la relatividad general. Además, consideramos tres tipos de interacciones fenomenológicas en el sector oscuro. Con el modelo propuesto obtuvimos las expresiones algebraicas para los parámetros cosmológicos de nuestro interés: los parámetros de desaceleración y coincidencia. Del mismo modo, comparamos gráficamente el modelopropuesto con el modelo ΛCDM.
