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

Figure 3

Same as Figure 2, but showing the spectra of (with different invariant masses ) produced by the Drell-Yan process in collisions at (a, c) and 1.96 TeV (b, d). The data points are quoted from the CDF (a, b) [48, 49] and D0 Collaborations (c, d) [50–52]. In all panels, is , see text in subsection 3.3 for the meanings of histograms which are quoted from QCD calculations.
