Query: Worldline Supersymmetry and Dimensional Reduction   For any worldline reformulation of a quantum field theory for Dirac fermions,
this paper shows that worldline supersymmetry may generally be enforced by the
vanishing of the commutator of the Dirac operator with the worldline
Hamiltonian. The action of supersymmetry on the worldline Lagrangian may not,
however, be written in terms of the variations on the fields in the usual way,
except when the spinning particle couples just to a one-form. By reduction from
six to four dimensions of the worldline reformulation for a spinning particle
coupled to a three-form, corrections to the superworldline Lagrangian are
presented which are needed in order to reproduce correct field theory results
from worldline perturbation theory in an unambiguous way.
