Gauge Fixing of Modified Cubic Open Superstring Field Theory    [PDF]

Maiko Kohriki, Taichiro Kugo, Hiroshi Kunitomo
The gauge-fixing problem of modified cubic open superstring field theory is
discussed in detail both for the Ramond and Neveu-Schwarz sectors in the
Batalin-Vilkovisky (BV) framework. We prove for the first time that the same
form of action as the classical gauge-invariant one with the ghost-number
constraint on the string field relaxed gives the master action satisfying the
BV master equation. This is achieved by identifying independent component
fields based on the analysis of the kernel structure of the inverse picture
changing operator. The explicit gauge-fixing conditions for the component
fields are discussed. In a kind of $b_0=0$ gauge, we explicitly obtain the NS
propagator which has poles at the zeros of the Virasoro operator $L_0$.
