We find that the EW correction $\\delta \\sigma_{\\mathrm{EW}}$ decreases the total cross section $\\sigma_{\\mathrm{NLO}} = \\sigma_{\\mathrm{LO}} + \\delta \\sigma_{\\mathrm{EW}}$ by -3\\% at Pb-Pb center-of-mass energy $\\sqrt{s_{NN}}=5.02$ TeV. The weak correction plays significant role whose contribution is about -4 times of that of QED.
