Dielectron production at midrapidity at low transverse momentum in peripheral and semi-peripheral Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV

Left panel: raw pT,ee-differential yield (S) in peripheral (70–90%) Pb–Pb collisions at √sNN = 5.02 TeV for 0.7 ≤ mee < 1.1 GeV/c2 overlaid with the opposite charge-sign distribution (OS) and the same charge-sign spectrum multiplied by the acceptance correction factor Racc (B). Right panel: signal over background as a function of pT,ee in peripheral (70–90%) Pb–Pb collisions at √sNN = 5.02 TeV for 0.7 ≤ mee < 1.1 GeV/c
