Variant N=1 supersymmetric non-Abelian Proca-Stueckelberg formalism in four dimensions

We present a new (variant) formulation of N = 1 supersymmetric compensator mechanism for an arbitrary non-Abelian group in four dimensions. We call this 'variant supersymmetric non-Abelian Proca-Stueckelberg formalism'. Our field content is economical, consisting only of the two multiplets: (i) A non-Abelian vector multiplet (A(mu)(I), lambda(I), C-mu nu rho(I)) and (ii) a compensator tensor multiplet (B-mu nu(I), chi(I), phi(I)). The index I is for the adjoint representation of a non-Abelian gauge group. The C-mu nu rho(I) is originally an auxiliary field Hodge-dual to the conventional auxiliary field D-I. The phi(I) and B-mu nu(I) are compensator fields absorbed respectively into the longitudinal components of A(mu)(I) and C-mu nu rho(I) which become massive. After the absorption, C-mu nu rho(I) becomes no longer auxiliary, but starts propagating as a massive scalar field. We fix all non-trivial cubic interactions in the total Lagrangian, and quadratic interactions in all field equations. The superpartner fermion chi(I) acquires a Dirac mass shared with the gaugino lambda(I). As an independent confirmation, we give the superspace reformulation of the component results.
