Mendonca, E. L. [UNESP]Dalmazi, D. [UNESP]2015-10-212015-10-212015-03-31Physical Review D, v. 91, n. 6, p. 1-9, 2015.1550-7998http://hdl.handle.net/11449/129476We present here a relationship among massive self-dual models for spin-3 particles in D = 2 + 1 via the Noether gauge embedment (NGE) procedure. Starting with a first-order model (in derivatives) S-SD(1) we have obtained a sequence of four self-dual models S-SD(i) where i = 1; 2; 3; 4. We demonstrate that the NGE procedure generates the correct action for the auxiliary fields automatically. We obtain the whole action for the fourth-order self-dual model including all the needed auxiliary fields to get rid of the ghosts of the theory.1-9engArtigo10.1103/PhysRevD.91.065037WOS:000352062800005Acesso restrito8279393876415608
