Pseudorapidity Distribution of Charged Particles and Square Speed of Sound Parameter in 𝑝-𝑝 or 𝑝-𝑝 Collisions over an Energy Range from 0.053 to 7 TeV

Figure 1

The pseudorapidity distributions, 𝑑𝑁_ch/𝑑𝜂, of charged particles produced in inelastic 𝑝-𝑝 collisions at √𝑠_𝑁𝑁=0.053 (a), 0.2 (b), 0.546 (c), and 0.9 TeV (d). The symbols represent the experimental data of the UA5 Collaboration [18], and the curves are our calculated results.
