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...

| Zusammenfassung: | 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
results of the literature. Adding totally symmetric source terms we provide an
unitarity analysis in $D$ dimensions. |
