Event Patterns Extracted from Transverse Momentum and Rapidity Spectra of Bosons and Quarkonium States Produced in pp and Pb-Pb Collisions at LHC

Figure 4

Event patterns in three-dimensional velocity () space in (a)-(b) pp collisions at  TeV and (c)-(d) Pb-Pb collisions at  TeV, for the (a)-(c) dimuon and (b)-(d) dielectron decay channels. The number of bosons for each panel is 1000. The red and blue globules represent the results of the first and second components in the two-component Erlang distribution for , respectively. The contributions of the first and second components in the two-component Gaussian distribution for are not distinguished by design.
