Statistical Behavior of Lepton Pair Spectrum in the Drell-Yan Process and Signal from Quark-Gluon Plasma in High-Energy Collisions

Figure 4

Same as Figure 2, but showing the spectra of [with different conditions (, , and )] produced by the Drell-Yan process in collisions at the LHC energies. The data points are quoted from the experiments performed by the ATLAS (a)–(d) [53–55], CMS (e) [56, 57], and LHCb Collaborations (f) [58–60]. The flavor of is shown in the panels, see text in subsection 3.3 for the meanings of histograms which are quoted from QCD calculations.
