Mendonça, E. L. [UNESP]Dalmazi, D. [UNESP]2018-12-112018-12-112015-03-31Physical Review D - Particles, Fields, Gravitation and Cosmology, v. 91, n. 6, 2015.1550-23681550-7998http://hdl.handle.net/11449/171830We 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) SSD(1) we have obtained a sequence of four self-dual models SSD(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.engArtigo10.1103/PhysRevD.91.065037Acesso aberto2-s2.0-849276111672-s2.0-84927611167.pdf
