Title: A skeleton in the cupboard: can 7Li come back?
Abstract: Unlike 2H, 3He and 4He, 7Li abundance data yield an extra constraint on cosmological parameters, on top of those deriving from CMB, BAO, SNIa or H0 data. This constraint, often disregarded, besides of favoring smaller baryon density values, indicates a preference for Dark Energy state equations well in the phantom regime, simultaneously softening the upper limit on the sum of neutrino masses, up to ~1.7eV.
