Transverse Momentum and Pseudorapidity Distributions of Charged Particles and Spatial Shapes of Interacting Events in Pb-Pb Collisions at 2.76 TeV

Figure 4

Extracted event shapes (dispersion plots) of 1000 charged particles at the stage of freeze-out in the momentum space (or ) in Pb-Pb collisions at  TeV in the centrality intervals (a) 0–5%, (b) 5–10%, (c) 10–20%, and (d) 20–30%. The closed circles, open circles, open squares, and closed squares represent orderly the contributions of leading target nucleons, target cylinder, projectile cylinder, and leading projectile nucleons from low to high in the longitudinal rapidity space.
(a) 2.76 TeV  Pb-Pb, 0–5%
(b) 5–10%
(c) 10–20%
(d) 20–30%
