The Conformal Equivalence of the half string 3-vertex and the Sciuto,Caneschi-schwimmer-veneziano 3-vertex

Abstract

In this paper we construct the operator connecting the three vertex in half string field theory and the dual model vertex of Sciuto, Caneshi Schwimmer and Veneziano (SCSV). This construction results in an explicit conformal transformation linking the two interactions in the matter sector at all levels. Thus establishing the equivalence in the matter sector between the two theories at least for N = 3.
