THE g-LOOP VACUUM IN THE NEVEU-SCHWARZ SECTOR BY OPERATOR SEWING OF DUAL VERTICES

Abstract

The matter part of the g-loop Reggeon vacuum of the Neveu-Schwara string is constructed by operator sewing of dual four-vertices using superfields. The economical parametrization of the locations of the external legs in the dual vertex leads to significant simplifications compared to ordinary sewing of three vertices. The final answer is in agreement with previous results, derived both through a mixture of path-integrals and sewing of three vertices, and through supersymmetrization of the bosonic result.
