dc.description.abstractWE CANONICALLY QUANTIZE (2+1)-DIMENSIONAL ELECTRODYNAMICS INCLUDING A HIGHER-DERIVATIVE CHERN-SIMONS TERM. THE EFFECTIVE THEORY DESCRIBES A STANDARD PHOTON AND AN ADDITIONAL DEGREE OF FREEDOM ASSOCIATED WITH A MASSIVE GHOST. WE FIND THE HAMILTONIAN AND THE ALGEBRA SATISFIED BY THE FIELD OPERATORS. THE THEORY IS CHARACTERIZED BY AN INDEFINITE METRIC IN THE HILBERT SPACE THAT BRINGS UP QUESTIONS ON CAUSALITY AND UNITARITY. WE STUDY BOTH OF THE LATTER FUNDAMENTAL PROPERTIES AND SHOW THAT MICROCAUSALITY AS WELL AS PERTURBATIVE UNITARITY UP TO ONE-LOOP ORDER ARE CONSERVED WHEN THE LEE-WICK PRESCRIPTION IS EMPLOYED.
