Description

We prove that any bilinear coupling of a massive spin-3/2 field can be brought into a gauge-invariant form suggested by Pascalutsa by means of a nonlinear field redefinition. The corresponding field transformation is given explicitly in a closed form and the implications for chiral effective field theory with explicit Δ(1232) isobar degrees of freedom are discussed.
