The Origin and Universality of “Spin Suppression” in Baryon Production

Abstract：

In high energy reactions the production of spin (3/2)⁺ baryons is strongly suppressed in comparison with that of (1/2)⁺ baryons. I show that the observed λ broken SU_f(3) symmetry in multihadron production is consistent with stochastic quark arrangement, and this self-consistency determines the ratios among SU_f(3) singlet, octet and decuplet, including all of their excited states. But for (1/2)⁺ and (3/2)⁺ baryon production, as in the case of the popular models, then the strangeness suppression factor λ=<N_S>/<N_u> completely determines the ratio of (3/2)⁺ to (1/2)⁺, and β=(1 + λ)/(3 + 2λ). The universality of this relation is emphasized.
