Abstract
We propose a new coupled three-form dark energy model to relieve the Hubble tension in this paper. Firstly, by performing a dynamical analysis with the coupled three-form dark energy model, we obtain four fixed points, including a saddle point representing a radiation dominated Universe, a saddle point representing a matter dominated Universe, and two attractors representing two saturated de Sitter Universes. Secondly, by confronting the coupled three-form dark energy model and the cold dark matter model (the CDM model) with cosmic microwave background (CMB), baryonic acoustic oscillations (BAO), Type Ia supernovae (SN Ia) observations, we obtain ( level) km/s/Mpc for the coupled three-form dark energy model and ( level) km/s/Mpc for the CDM model, the former is in strong tension with the latest local measured value at confidence level, while the latter is in strong tension with the latest local measured value at level.
