Abstract:
We report on measurements of the dijet pseudorapidity distributions in pp and pPb collisions at sNN=5.02 TeV\sqrt{s_\mathrm{NN}}= 5.02~\mathrm{TeV} with the CMS detector. These measurements are sensitive to nuclear modifications of parton distribution functions (PDF). Recent theoretical studies based on NLO calculations show that the constraining power of pPb data on nuclear PDF fits can be improved by the knowledge of the corresponding measurement in pp collisions. Moreover, measurements of dijet average transverse momentum provide a good handle on Q2Q^2. In this physics analysis summary, the dijet pseudorapidity spectra are studied in different dijet average transverse momentum intervals. These measurements can provide constraints on the nuclear PDF over a wide phase space of xx and Q2Q^2.
