We show that the data on inclusive cross-sections for light mesons and baryons in high energy hadron-hadron interactions are consistent with a simple empirical formula σ incl = a (2J + 1) (2I m + 1) exp(−bM 2) observed recently in e +e − annihilations, where J is the spin, I m is a modified isospin and M is the mass of the produced particle. The same value of the slope parameter b is observed for e +e − annihilations at PEP/PETRA and LEP energies and for proton-proton interactions at ISR energies. This universal dependence points to a simple mass law for hadron states produced locally in string fragmentation irrespective of the configuration of the strings in various processes.
