TLDR
In this article, the general dual vertex describing the transition of a Ramond fermion into a Neveu-Schwarz meson by the emission of general excited fermions was constructed.Abstract:
We construct the general dual vertex describing the transition of a Ramond fermion into a Neveu-Schwarz meson by the emission of a general excited fermion state. Our vertex thus generalizes the previous results of Thorn and Schwarz and is now put into a relatively compact and manageable form which enables us to check that certain of the general gauge conditions are correctly converted between the meson and fermion legs by the vertex. The particular construction of the vertex can be applied to the other older dual theories and leads to some new insights into them.read more

The Conformal Field Theory of Orbifolds
TL;DR: In this article, the authors derived Yukawa couplings in the effective field theory for fermionic strings on orbifolds and applied them to the scattering of four twisted string states, which allowed the extraction of operator product coefficients of conformal twist fields.

Supersymmetrical Dual String Theory
Michael B. Green,John H. Schwarz +1 more
TL;DR: In this paper, it was proved that the physical states of the open-string sector of the ten-dimensional string theory form supersymmetry multiplets, and the proof was achieved by first constructing a new formulation of the spectrum generating algebra, and then forming the supersymmetric operator (as well as associated operators) and demonstrating that it transforms as a spinor under Lorentz transformations and has the correct anticommutation relations.

Conformal techniques, bosonization and tree-level string amplitudes
TL;DR: In this article, a simple representation of the cocycle operators that are needed for bosonization of conformal operators, including spin fields and ghosts, is given, and a typical calculation of a four-point amplitude in the o(16) × o (16) heterotic string is presented in manifestly Lorentz-covariant form.

Superstring Theory Vol. 1 : 25th Anniversary Edition
TL;DR: In this article, a self-contained introduction to superstrings, Volume 1 begins with an elementary treatment of the bosonic string, before describing the incorporation of fermionic degrees of freedom leading to supersymmetry and internal quantum numbers leading to gauge interactions.

Factorizable dual model of pions.
André Neveu,John H. Schwarz +1 more
TL;DR: In this paper, a dual-resonance model of mesons is constructed through the use of creation and annihilation operators having simple anticommutation properties as well as harmonic-oscillator type operators of the conventional model.

Dual Theory for Free Fermions
TL;DR: In this paper, a wave equation for free fermions is proposed based on the structure of the dual theory for bosons, which preserves the role played by the Virasoro algebra.

Quark Model of Dual Pions
André Neveu,John H. Schwarz +1 more
TL;DR: In this paper, the same pseudoscalar pions are incorporated into Ramond's model of free dual fermions, by considering the emission of $N ε-ensuremath{-1$ pions and factorizing in the quark-antiquark channel.

The operator approach to dual multiparticle theory
TL;DR: In this paper, a new technique is introduced, which allows a comprehensive and simple treatment of operatorial manipulations, and is based on the underlying 0(2;1) symmetry of the dual resonance model.

Duality in operator formalism
S. Fubini,Gabriele Veneziano +1 more
TL;DR: In this paper, a form for a dual resonant amplitude in which both duality and factorization are explicitly exhibited was proposed, and the transformation properties of the operators appearing in the model under the fundamental projective transformation of Koba and Nielsen were investigated.
