| Özet |
| The pseudorapidity distributions of dijets as functions of their average transverse momentum () are measured in proton-lead () and proton-proton () collisions. The data samples were collected by the CMS experiment at the CERN LHC, at a nucleon-nucleon center-of-mass energy of 5.02 TeV. A significant modification of the spectra with respect to the spectra is observed in all intervals investigated. The ratios of the and distributions are compared to next-to-leading order perturbative quantum chromodynamics calculations with unbound nucleon and nuclear parton distribution functions (PDFs). These results give the first evidence that the gluon PDF at large Bjorken in lead ions is strongly suppressed with respect to the PDF in unbound nucleons. |
