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 2

The pseudorapidity distributions of charged particles in inelastic 𝑝-𝑝 collisions at √𝑠_𝑁𝑁=0.2 (a) and 0.41 TeV (b), as well as in inelastic 𝑝-𝑝 collisions at √𝑠_𝑁𝑁=0.54 (c), 0.63 (d, e), and 1.8 TeV (f). The symbols represent the experimental data of the PHOBOS [19] (a, b), UA1 [20] (c), P238 [21] (d), and CDF Collaborations [22] (e, f), respectively. The curves are our calculated results.
