THE COMING BACK OF THE PROCA FIELD

Romero C., Duarte M.P.

A new version of the old Weyl’s unified field theory based on a strict application of the principle of gauge invariance leads to the appearance of a massive vector field, which has an entirely geometric nature and can be interpreted, under some conditions, as the Proca field. We investigate some possible consequences of the presence of this field in the modern astrophysical scenario.
