Unitarity of Singh-Hagen Model in DimensionsDOI: https://doi.org/10.1155/2020/8425745 Abstract: The particle content of the Singh-Hagen model (SH) in 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 results of the literature. Adding source terms, we provide a unitarity analysis in dimensions. In addition, we have also analyzed the positivity of the massless Hamiltonian
