- In theoretical physics, the Veneziano amplitude refers to the discovery made in 1968 by Italian theoretical physicist Gabriele Veneziano that the Euler beta function, when interpreted as a scattering amplitude, has many of the features needed to explain the physical properties of strongly interacting mesons, such as symmetry and duality. Conformal symmetry was soon discovered. This discovery can be considered the birth of string theory, as the discovery and invention of string theory came about as a search for a physical model which would give rise to such a scattering amplitude. In particular, the amplitude appears as the four tachyon scattering amplitude in orientated open bosonic string theory. Using Mandelstam variables and the beta function , the amplitude is given by where is the string constant, are the tachyon four-vectors, is the open string theory coupling constant, and . (en)
- L'ampiezza di Veneziano è una grandezza fisica interpretabile come una particolare ampiezza di diffusione di una particolare sezione d'urto. Introdotta dal fisico Gabriele Veneziano nel 1968 sfruttando empiricamente la funzione beta di Eulero, divenne ben presto uno dei presupposti fondamentali che portò all'elaborazione della teoria delle stringhe.
