摘要：
The path integral quantization for higher derivative Chern-Simons theories in (2+1) dimensions coupled to fermions is treated. The diagrammatic and the Feynman rules are constructed and the regularization and renormalization of this higher derivative model are analyzed in the Framework of the perturbation theory. Finally, the unitarity problem related to the possible appearance of ghost states with negative norm is also discussed.
