Abstract :

One of the key open problems in solving N=4 Super-Yang-Mills theory
is the determination of OPE coefficients. We are searching for a framework
which could, in principle, serve to determine the OPE coefficients
at any value of the coupling. One such framework might be the
string field theory vertex which up till now could be determined
only for a free worldsheet theory. In this talk I will describe
a novel approach to the string field theory vertex which
should be applicable for any interacting but integrable worldsheet
theory.
