Figure Information Scope: PWG PWG-EM (Electromagnetic probes) Energy 13 TeV System p-p Figure Group [EPS&QM2023] - Virtual photon production in MB and high multiplicity pp collisions at 13TeV Figure Image Figure image (.eps) photon_pt_hm_0.eps Figure image (.pdf) photon_pt_hm_0.pdf Figure Caption Direct photon spectrum as a function of pT in high-multiplicity events. Finite bin width correction is applied to pt-direction. Due to issue of HM prompt photon, Shen's HM calculation is not shown at HM.
