Nrf. Braga et H. Montani, BRST QUANTIZATION OF THE CHIRAL SCHWINGER MODEL IN THE EXTENDED FIELD-ANTIFIELD SPACE, Physical review. D. Particles and fields, 49(2), 1994, pp. 1077-1080
It is shown that the quantization of the chiral Schwinger model in the
Batalin-Vilkovisky framework can be carried out in an extended space
of fields and antifields, where the master equation has a local soluti
on. The Wess-Zumino term is generated in this way, avoiding the use of
nonlocal expressions. The nilpotency of the new BRST charge is proven
explicitly.
