Reparametrization ghost contribution to superstring multiloop amplitudes.
We use the sewing procedure in the operator formalism to construct the N-point g-loop vertex VN;g for the (b,c) system in superstring theory. After computing explicitly the lowest picture-changed states, we saturate VN;g with them showing that the reparametrization ghost contribution to g-loop super...
