$\theta$ Effects in Chern-Simons ${\mathrm{QED}}_{2+1}$ with a Four-Fermi Interaction

Junegone Chay, Deog Ki Hong, Taejin Lee +1

We investigate the effects of the Chern-Simons coupling on the high energy behavior in the $(2+1)$-dimensional Chern-Simons QED with a four-Fermi interaction. Using the $1/N$ expan…
