A Dark Energy model from Generalized Proca Theory
read the original abstract
We consider a specific dark energy model, which only includes the Lagrangian up to the cubic order in terms of the vector field self-interactions in the generalized Proca theory. We examine the cosmological parameters in the model by using the data sets of CMB and CMB+HST, respectively. In particular, the Hubble constant is found to be $H_0=71.80^{+1.07}_{-0.72}$ ($72.48^{+0.72}_{-0.60}$) $\rm kms^{-1}Mpc^{-1}$ at $68\%$~C.L. with CMB (CMB+HST), which would alleviate the Hubble constant tension. We also obtain that the reduced $\chi^2$ values in our model are close to unity when fitting with CMB and CMB+HST, illustrating that our model is a good candidate to describe the cosmological evolutions of the universe.

Cosmological tensions in Proca-Nuevo theory
Fitting a one-parameter vector-tensor dark energy model to CMB, BAO, and supernova data reduces the Hubble tension to about 1.5–2σ, but the preference over ΛCDM is weak and disappears once full perturbations are included.
