Figure 1: Dependence of charged particle background p t density ρ on uncorrected multiplicity of tracks used for jet finding (|η| < 0.9)
Figure 2: δ p t of random cones in the 10% most central Pb–Pb events for the three types of random cone probes with p min t = 0.15 GeV/c
Figure 3: δ p t distribution for random cones, averaged over the full azimuth and separated for three bins of random cone azimuthal orientations with respect to the measured event plane
Figure 4: Dependence of the standard deviation of the δ p t distributions on uncorrected charged particle multiplicity, compared to the limit derived from the measured track p t spectrum (Equation 3) and from additional elliptic and triangular flow contrib
