Multi Particle Dual Model

Abstract

The multiparticle dual model is a generalisation of the simple Beta-function model for two-particle scattering introduced by Veneziano [1]. For the elastic scattering of two identical particles, A, of mass m,

$$A({p_1}) + A({p_2}) \to A({p_3}) + A({p_4})$$

we have as the invariant amplitude T = B(−α(s), −α((t)) + two other crossed terms. Here

$$\alpha (s) = {\alpha _o} + \alpha 's$$

(1.1)

and

$$[s = {({p_1} + {p_2})^2},t = {({p_3} - {p_2})^2}.$$
