Query: Rarita-Schwinger Quantum Free Field Via Deformation Quantization   Rarita-Schwinger (RS) quantum free field is reexamined in the context of
deformation quantization. It is found out that the subsidiary condition does
not introduce any change either in the Wigner function or in other aspects of
the deformation quantization formalism, in relation to the Dirac field case.
This happens because the vector structure of the RS field imposes constraints
on the space of wave function solutions and not on the operator structure. The
RS propagator was also calculated within this formalism.
