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

Figure 1

The transverse momentum distributions of (a) 𝜋⁻, 𝐾⁻, and 𝑝, (b) 𝜋⁺, 𝐾⁺, and 𝑝, (c) 𝜋⁺, (d) 𝐾⁺, and (e) 𝑝 produced in 𝑝𝑝 collision at √𝑠=200 GeV with different𝑦ranges and magnifications are shown in the figure. The symbols represent the experimental data of the STAR [26] and BRAHMS Collaborations [27] and the curves are our results calculated by the Boltzmann or two-component Boltzmann distribution.
