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_mb.eps Figure image (.pdf) photon_pt_mb.pdf Figure Caption Direct photon spectrum as a function of pT. gamma_{dir} is calculated as gamma_{decay} x r/ (1-r). Finite bin width correction is applied to pt-direction.
