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 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 H 0 = 67 . 8 − 0 . 6 + 0 . 7 ( 1 σ level) km/s/Mpc for the coupled three-form dark energy model and H 0 = 67 . 6 − 0 . 5 + 0 . 5 ( 1 σ level) km/s/Mpc for the Λ CDM model, the former is in strong tension with the latest local measured H 0 value at 4 . 3 σ confidence level, while the latter is in strong tension with the latest local measured H 0 value at 5 . 1 σ level.
