On vector-tensor minimally coupled field theories

We consider vector-tensor minimally coupled Lagrangians, i.e., scalar densities of the form ℒ = g1/2R +L(gij;Ψi;Ψi,j). We prove that the gauge invariance of any of the sets of Euler-Lagrange expressions implies the gauge invariance of the Lagrangian itself for n even, and an "almost" gauge...

description We consider vector-tensor minimally coupled Lagrangians, i.e., scalar densities of the form ℒ = g1/2R +L(gij;Ψi;Ψi,j). We prove that the gauge invariance of any of the sets of Euler-Lagrange expressions implies the gauge invariance of the Lagrangian itself for n even, and an "almost" gauge invariance for n odd. We also find those ℒ for which Ei(ℒ) = 0 or Eij(L) = 0, generalizing well-known results by Lovelock and a result by the authors. © 1986 Plenum Publishing Corporation.
