Transverse Momentum Distributions of Final-State Particles Produced in Soft Excitation Process in High Energy Collisions

Figure 9

The transverse momentum distributions of (a) 𝜋⁻, 𝐾⁰_𝑆+𝐾⁻, and 𝑝, (b) 𝜋⁰, (c) 𝑝, and (d) Ξ and Ω produced in Pb-Pb collisions at √𝑠_𝑁𝑁=2.76 TeV ((a), (b), and (c)) and pp collision at √𝑠=2.76 and 7 TeV ((b) and (d)) with different𝑦ranges, centrality classes, and magnifications are shown in the figure. The symbols represent the experimental data of the ALICE Collaboration [35–38] and the curves are our results calculated by the Boltzmann or two-component Boltzmann distribution.
