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

TL;DR

This paper constructs an explicit conformal transformation linking the half string field theory 3-vertex with the SCSV 3-vertex, establishing their equivalence in the matter sector at all levels for N=3.

Contribution

It provides the first explicit operator connecting the two vertices, demonstrating their conformal equivalence in the matter sector at all levels.

Findings

The operator explicitly links the two vertices.

The equivalence holds at all levels for N=3.

The construction confirms the matter sector equivalence.

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.
