Unfortunately, string field theory is in a rather primitive state right now, and not even close to being as well understood as ordinary (particle) field theory. Of course, this is exactly the reason why the present is the best time to do research in this area.

Conformal Field Theory (for string theorists) - C.N. Yang ...

insti.physics.sunysb.edu

To date in this class, string theory boils down to the study four free (quadratic) quantum eld theories: one for the X elds, one for the elds, one for the bcghost system, and one for the ghost system.
