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

Figure 8

The transverse momentum distributions of (a) 𝜋⁻, 𝐾⁻, and 𝑝, (b) 𝜋⁺, 𝐾⁺, and 𝑝, (c) 𝐾⁰_𝑆,Λ, Λ, 𝜙, and Ξ⁺+Ξ⁻, and (d) charged particles in range of |𝜂|<0.8 in NSD produced in pp collisions at √𝑠=900 GeV with different magnifications are shown in the figure. The symbols represent the experimental data of the ALICE Collaboration [33, 34] and the curves are our results calculated by the Boltzmann or two-component Boltzmann distribution.
