Proca theory from the spinning worldline

A bstract We obtain Proca field theory from the quantisation of $$ \mathcal{N} N = 2 supersymmetric worldline upon supplementing graded BRST-algebra with an extra multiplet oscillators. The linearised describes BV-extended spectrum theory, together a Stückelberg field. When coupling to background fields we derive equations, arising as consistency conditions in BRST procedure. also explore non-abelian modifications, complexified vector well dilaton propose cubic action on space BRST-operators which reproduces known action.
