Elastic interactions are introduced in the simulations. The elastic cross sections vary from different hadrons and energy scales, which can qualitatively explain the different collective motions of various hadrons.5 pages, 4 figuresNuclear TheoryHigh Energy Physics - PhenomenologyNuclear Experimenttext
