In this letter, we propose to introduce a new Abelian gauge field Bμ corresponding to the so-called β symmetry into the normal Quantum Electrodynamics in 2+1 dimensions (QED3) of γ representation. The resulting theory is shown to be equivalent to QED3 containing two flavors of two-component fermions with mass of an opposite sign. We also show that Bμ field can generate a Chern-Simons term in...
