A dark energy model from generalized Proca theory

We consider a specific dark energy model, which only includes the Lagrangian up to cubic order in terms of vector field self-interactions generalized Proca theory. examine cosmological parameters model by using data sets CMB and CMB+HST, respectively. In particular, Hubble constant is found be H0=71.80?0.72+1.07 (72.48?0.60+0.72) kms?1Mpc?1 at 68% C.L. with (CMB+HST), would alleviate tension. also obtain that reduced ?2 values our are close unity when fitting illustrating good candidate describe evolutions universe.
