New explanation of the strange baryon rapidity distributions in ultra-relativistic nucleus-nucleus collisions Original Research Article

A model of multiparticle production in hadronic collisions at ultra-relativistic energies, based on the assumption of independent string fragmentation, reproduces the rapidity spectra of Λ and View the MathML source in sulphur-sulphur collisions reported by the NA35 Collaboration. This is achieved after a reconsideration of the intermediate multi-string states and the structure of the diquarks. Nuclear stopping power is also studied through the computation of the View the MathML source rapidity spectra.
