Abstract
We have investigated the generalized QCD ghost model of dark energy (DE) in the framework of Einstein–Aether gravity. At first we have discussed the noninteracting generalized ghost DE (GGDE) model in flat Friedmann–Robertson–Walker (FRW) universe and then we have generalized the discussion to the interacting GGDE model in flat and nonflat universe. According to this, we have analyzed the nature of the equation of state (EoS) parameter, deceleration parameter and slow-roll parameters. We have used the sign of square speed of sound to determine the stability of the model in different cases. Also, we have analyzed [Formula: see text] plane in graphically and pointed out freezing region and thawing region in that plane. Then we enlarge our discussion to verify the effectiveness of this model under investigation by analyzing the statefinder diagnosis parameters for the present cosmological setup. The nature of slow-roll parameters in both scenarios with and without interactions has been shown diagrammatically.
