| Incoherent J/ photoproduction in heavy ion ultraperipheral collisions (UPCs), in which the photon interacts with localized, fluctuating gluonic hotspots rather than the entire nucleus, provides a unique probe of those fluctuations. This study presents the first measurement of the dependence of this photoproduction yield on the photon-nucleon center-of-mass energy (), using PbPb UPCs at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The data corresponds to an integrated luminosity of 1.52 nb, recorded by the CMS experiment. The measurement covers a wide range of 40-400 GeV, probing gluons carrying a fraction of nucleon momentum in the range between 5.9 10 and 6.5 10. The measured incoherent J/ photoproduction cross section is suppressed relative to theoretical predictions without nuclear effects. However, the ratio of incoherent to coherent photoproduction remains constant across the probed and range. Together, these results pose significant challenges to current theoretical models which include gluon saturation or nuclear shadowing effects. |
