The space-time operator product expansion in string theory duals of field theories


We study the operator product expansion (OPE) limit of correlation functions in field theories which possess string theory duals, from the point of view of the string worldsheet. We show how the interesting (“single-trace”) terms in the OPE of the field theory arise in this limit from the OPE of the worldsheet theory of the string dual, using a dominant… (More)
