The Lee-Wick-Chern-Simons pseudo-quantum electrodynamics (2504.15444v1)

Abstract: The Lee-Wick pseudo-quantum electrodynamics in the presence of a Chern-Simons term is studied in this paper. The paper starts with a non-local lagrangian density that sets the Lee-Wick electrodynamics defined on a bidimensional space added to the Chern-Simons topological term. We investigate classical aspects as the potential energy for the interaction of static charges through the gauge propagator. The gauge field of the Lee-Wick-Chern-Simons electrodynamics is minimally coupled to the fermions sector that includes new degree of freedom, as a Lee-Wick heavy fermion partner of the electron. The perturbative approach for the theory is presented via effective action in which we obtain the Ward identities. We study the radiative corrections at one loop for the electron self-energy, the vacuum polarization, and the $3$-vertex through the Ward identity. We show that the Lee-Wick mass has a fundamental role in these results.
