Universality Principle for Orbital Angular Momentum and Spin in Gravity with Torsion

Abstract

We argue that compatibility with elementary particle physics requires gravitational theories with torsion to be unable to distinguish between orbital angular momentum and spin. An important consequence of this principle is that spinless particles must move along autoparallel trajectories, not along geodesics.
