Veneziano amplitude



String theory

Quantum field theory



The Veneziano amplitude is the 1-loop string scattering amplitude for the scattering of four open bosonic strings in their tachyon states. Hence equivalently it is a certain 4-point function in a certain boundary 2d CFT.

Historically, this amplitude first arose in dual resonanace models? and the realization that it has a natural interpretation as the scattering of strings was one of the main original motivations for the development of string theory.
