Sažetak
The pseudorapidity distributions of dijets as functions of their average transverse momentum (paveT) aremeasured in proton-lead (pPb) and proton-proton (pp) collisions. The data samples were collected by theCMS experiment at the CERN LHC, at a nucleon-nucleon center-of-mass energy of 5.02 TeV. A significantmodification of thepPb spectra with respect to theppspectra is observed in allpaveTintervals investigated.The ratios of thepPb andppdistributions are compared to next-to-leading order perturbative quantumchromodynamics calculations with unbound nucleon and nuclear parton distribution functions (PDFs).These results give the first evidence that the gluon PDF at large Bjorkenxin lead ions is stronglysuppressed with respect to the PDF in unbound nucleons
