Query: Gauge Invariant 1PI Effective Superstring Field Theory: Inclusion of the
  Ramond Sector   We construct off-shell amplitudes in heterotic and type II string theories
involving arbitrary combination of Ramond and Neveu-Schwarz sector external
states. We also construct the equations of motion of a gauge invariant 1PI
effective field theory which reproduces these off-shell amplitudes. Using this
construction we prove that the renormalized physical masses do not depend on
the choice of local coordinate system and locations of picture changing
operators used in defining the off-shell amplitudes. We also use this formalism
to examine the conditions under which space-time supersymmetry is unbroken in
the quantum theory.
