Abstract
In a previous work the authors discussed the action for a massless relativistic point particle with a gauged N-extended worldline supersymmetry that yields, upon quantisation, a relativistic wave equation for pure spin N/2. They present further details, emphasising the N=2 particle model for which a wavefunction with O(2) charge q can be interpreted as the field strength of a (q-1)-form gauge potential. They present extensions of this model that yield field equations for massless and massive antisymmetric tensors in arbitrary spacetime dimension d. They show how to obtain chirality and generalised self-duality conditions.
