The Beginning of String Theory: A Historical Sketch
Abstract
In this note we follow the historical development of the ideas that led to the formulation of String Theory. We start from the inspired guess of Veneziano and its extension to the scattering of N scalar particles, then we describe how the study of its factorization properties allowed to identify the physical spectrum, and finally we discuss how the critical values of the intercept of the Regge trajectory and of the critical dimension were fixed to be α_0 =1 and d=26.
