Abstract
I introduce (Extended) Proca-Nuevo, a non-linear theory of a massive spin-1 field enjoying a non-linearly realized constraint. I will provide a covariantization scheme that allows for consistent, ghost-free cosmological solutions, describing the correct number of dynamical variables in the presence of perfect fluid matter. I will finally exhibit explicit hot Big Bang solutions featuring a late-time self-accelerating epoch, where all the stability and subluminality conditions are satisfied and where gravitational waves behave precisely as in General Relativity.
