Query: Chirality and parity in a first-quantized representation   We study the realization of chiral and parity transformations within a
particle-like path-integral representation for Dirac fields, showing how those
transformations can be implemented in a natural way within the formalism. We
then obtain a representation for the chiral fermion propagator and determinant
within this framework, and also formulate a way to define the average of the
propagator over a random mass in $d=2n$ dimensions.
