| contents | In this paper, we extend our previous results on the gravitational interactions for massive spin 5/2 particles and spin 3 particles to massive spin 7/2, including its massless and partially massless limits. These results share some common features, such as a non-singular massless limit in $AdS$ and a flat limit for non-zero masses, as well as a singularity at the points corresponding to the boundary of the unitary forbidden region. At the same time, these results allow us to suggest what the structure of non-minimal interactions for arbitrary spins looks like. Another subject of interest is the Skvortsov-Vasiliev formalism for describing partially massless fields. This formalism has been very useful in our research, but our examples have shown that it dos not always lead to the correct results. |
