• TITLE: Direct Derivation of the Comma 3-Vertex in the Full String Basis

  AUTHORS: A. Abdurrahman, M. Gassem

  KEYWORDS: String Theory, Witten’s Theory, Open Bosonic String

  JOURNAL NAME: Journal of Modern Physics, Vol.10 No.10, September 29, 2019

  ABSTRACT: The interacting comma 3-vertex for the bosonic open string in the full string basis is derived using the half string overlap relations directly. Thus avoiding the coherent states technique employed in earlier derivations. The resulting form of the interacting 3-vertex turns out to be precisely the desired expression obtained in terms of the full string oscillator modes. This derivation establishes that the comma 3-vertex and Witten’s 3-vertex are identical and therefore are interchangeable.
