Abstract: (Elsevier)
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 Λ cold dark matter model (the Λ CDM model) with cosmic microwave background (CMB), baryonic acoustic oscillations (BAO), Type Ia supernovae (SN Ia) observations, we obtain H0=67.8−0.6+0.7 ( 1σ level) km/s/Mpc for the coupled three-form dark energy model and H0=67.6−0.5+0.5 ( 1σ level) km/s/Mpc for the Λ CDM model, the former is in strong tension with the latest local measured H0 value at 4.3σ confidence level, while the latter is in strong tension with the latest local measured H0 value at 5.1σ level.Note:
