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

Figure 1

(a)-(b) Transverse momentum spectra and (c)-(d) rapidity spectra of bosons produced in pp collisions at  TeV, for the (a)-(c) dimuon () and (b)-(d) dielectron (ee) decay channels in and , respectively, where on the vertical axis denotes the cross section, and the integral luminosity  . The closed squares represent the experimental data of the CMS Collaboration [27], and the error bars are only the statistical uncertainties. The curves are our results calculated by using the (a)-(b) two-component Erlang distribution and (c)-(d) two-component Gaussian distribution, respectively.
