Unitarity of Singh-Hagen Model in D Dimensions

Unitarity of Singh-Hagen Model in D Dimensions

The particle content of the Singh-Hagen model (SH) in D dimensions is revisited. We suggest a complete set of spin-projection operators acting on totally symmetric rank-3 fields. We give a general expression for the propagator and determine the coefficients of the SH model confirming previous result...
