We quantize the bosonized chiral Schwinger model by using the systematic Batalin-FradkinVilkovisky formalism. We derive a Becchi-Rouet-Stora-Tyutin gauge-fixed covariant action showing that the auxiliary fields introduced in the formalism turn into the Wess-Zumino scalar.
We quantize the self-dual massive theory by using the Batalin-Tyutin Hamiltonian method, which systematically embeds a second class constraint system into a first class one in extended phase space by introducing new fields. Through this analysis we obtain simultaneously the Stiickelberg scalar term related to the explicit gauge-breaking effect and a new type of Wess-Zumino action related to the Chern-Simons term.
