TL;DR

This paper develops a composite superstring model for hadrons incorporating extended Virasoro superconformal symmetry, ensuring consistent amplitudes without negative norm states by imposing supercurrent constraints.

Contribution

It introduces a novel composite string framework for hadrons with extended symmetry and supercurrent conditions to eliminate unphysical states.

Findings

Extended Virasoro superconformal symmetry achieved

String amplitudes are consistent with physical state conditions

Supercurrent constraints remove negative norm states

Abstract

Hadron dynamics is formulated in terms of interacting composite strings. Consistent composite string model with extended Virasoro superconformal symmetry is found. These composite strings carry flavour and chiral degrees of freedom on edging two-dimensional surfaces. Necessary correct description of string amplitudes without states of negative norms in the spectrum of physical states is reached when special supercurrents conditions are fulfilled.
