What type of particles do representations of so(3) other than j=1/2 or j=1 correspond to?

For j=1/2 with have spin-half particles, for j=1 with have spin-one particles. So for j=3/2 and j=2, do we get particles with spin-3/2 and spin-2? I remember reading somewhere that spin-2 particles like the graviton must be described by a traceless symmetric tensor.

thanks

Gravitino and graviton. Accounted for in a supersymmetric theory of gravity, also known as supergravity. The simplest theory assumes a supermultiplet of only 2 particles, a quanta of spin 3/2 and a quanta of spin 2.

A lot of unstable hadrons have spins>3/2
