| Özet |
| Incoherent photoproduction in heavy ion ultraperipheral collisions (UPCs) provides a sensitive probe of localized, fluctuating gluonic structures within heavy nuclei. This Letter reports the first measurement of the photon-nucleon center-of-mass energy () dependence of this process in PbPb UPCs at a nucleon-nucleon center-of-mass energy of 5.02 TeV, using of data recorded by the CMS experiment. The measurement covers a wide range of , probing gluons carrying a fraction of nucleon momentum down to an unexplored regime of . Compared to baseline predictions neglecting nuclear effects, the measured cross sections exhibit significantly greater suppression at lower . Additionally, the ratio of incoherent to coherent photoproduction is found to be constant across the probed and range, disfavoring the establishment of the black disk limit. This Letter provides critical … |
