  It was suggested that light-cone superstring field theory (LCSFT) and matrix
string theory (MST) are closely related. Especially the bosonic twist fields
and the fermionic spin fields in MST correspond to the string interaction
vertices in LCSFT. Since CFT operators are characterized by their OPEs, in our
previous work we realized the most important OPE of the twist fields by
computing contractions of the interaction vertices using the bosonic cousin of
LCSFT. Here using the full LCSFT we generalize our previous work into the
realization of OPEs for a vast class of operators.
