In the invariant mass range of 0.4 $<$$M_{ee}$$<$ 2.6 GeV/$c^{2}$ at low transverse momentum ($p_{\\rm T}$$ < $0.15 GeV/$c$), the yields increase while the pair $\\sqrt{\\langle p_{\\rm T}^{2} \\rangle}$ decreases with increasing $\\sqrt{s_{_{\\rm{NN}}}}$, a feature is correctly predicted by the QED calculation. The energy dependencies of the measured quantities are sensitive to the nuclear form factor, infrared divergence and photon polarization. The data are compiled and used to extract the charge radius of the Au nucleus.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.153885.v1/t1","@type":"Dataset","description":"'54.4 GeV, Centrality: 40-60%'","name":"Table from Fig. 6(a)"},{"@id":"https://doi.org/10.17182/hepdata.153885.v1/t2","@type":"Dataset","description":"'54.4 GeV, Centrality: 60-80%'","name":"Table from Fig. 6(b)"},{"@id":"https://doi.org/10.17182/hepdata.153885.v1/t3","@type":"Dataset","description":"'54.4 GeV, Centrality: 80-100%'","name":"Table from Fig. 6(c)"},{"@id":"https://doi.org/10.17182/hepdata.153885.v1/t4","@type":"Dataset","description":"'200 GeV, Centrality: 80-100%'","name":"Table from Fig. 6(d)"},{"@id":"https://doi.org/10.17182/hepdata.153885.v1/t5","@type":"Dataset","description":"'54.4 GeV, Centrality: 40-60%'","name":"Table from Fig. 7(a)"},{"@id":"https://doi.org/10.17182/hepdata.153885.v1/t6","@type":"Dataset","description":"'54.4 GeV, Centrality: 60-80%'","name":"Table from Fig. 7(b)"},{"@id":"https://doi.org/10.17182/hepdata.153885.v1/t7","@type":"Dataset","description":"'54.4 GeV, Centrality: 80-100%'","name":"Table from Fig. 7(c)"},{"@id":"https://doi.org/10.17182/hepdata.153885.v1/t8","@type":"Dataset","description":"'200 GeV, Centrality: 80-100%'","name":"Table from Fig. 7(d)"},{"@id":"https://doi.org/10.17182/hepdata.153885.v1/t9","@type":"Dataset","description":"'$0.4 &lt;
