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

Figure 3

The transverse momentum distributions of (a) 𝜋⁻, 𝐾⁻, and 𝑝 as well as (b) 𝜋⁺, 𝐾⁺, and 𝑝 produced in d-Au collisions at √𝑠_𝑁𝑁=200 GeV with |𝑦|<0.1 and different centrality classes and magnifications are shown in the figure. The symbols represent the experimental data of the STAR Collaboration [26] and the curves are our results calculated by the Boltzmann or two-component Boltzmann distribution.
