Gauge fixing of open superstring field theory in the Berkovits non-polynomial formulation

Abstract

We consider gauge fixing of open superstring field theory formulated by Berkovits, concentrating on the Neveu-Schwarz sector. In the free theory, we perform gauge fixing completely, which requires infinitely many ghosts and antighosts carrying various world-sheet ghost numbers and picture numbers. In the interacting theory, we have determined the form of interactions cubic in fields and antifields in the Batalin-Vilkovisky formalism.
