On-shell Gauge Invariants and Field Strengths in Open Superstring Field Theory
arXiv:hep-th/0406242 · doi:10.1016/j.nuclphysb.2004.07.043
Abstract
We study gauge invariant quantities in the open superstring field theory proposed by Berkovits, extending the precedent discussion in bosonic string field theory. Our gauge invariants are ``on-shell''. As its applications, we define quantities which are expected to be related to the U(1) field strength -- a RR coupling and a ``component'' of the string field equation of motion, and consider their naive extensions to off-shell. Order by order calculations show that the field strength extracted from the RR coupling is not gauge invariant, while from the component of the equation of motion we obtain an off-shell field strength which is gauge invariant under full gauge transformation if on-shell, and under linearized gauge transformation even off-shell.
