Validity of Gauge-Fixing Conditions and the Structure of Propagators in Open Superstring Field Theory

Understand

We make a detailed analysis on validity of gauge-fixing conditions and the structure of propagators in the Wess-Zumino-Witten-type open superstring field theory.

• First, we generalize the gauge-fixing conditions considered in JHEP 03 (2012) 030 [arXiv:1201.1761] by the present author et al., and propose a large class of conditions characterized by zero modes of world-sheet oscillators.
• Then we demonstrate its validity: we prove that gauge degrees of freedom allow us to impose the conditions, and that the conditions fix the gauges completely.
• Moreover, we elucidate how the information about the gauge choices is reflected in the structure of propagators.
