Good question. All I can say is that we haven't seen (experimentally)
any particles that can be described as a third rank tensor. I don't
think QFT predicts a particle of this type, but I don't see why
superstring theory doesn't. There may be some symmetry arguments in
the theories that don't allow for a particle like this.
