Аннотация:Inclusive jet production in pPb collisions at a nucleon-nucleon (NN) center-of-mass energy of sqrt(s[NN])=5.02 TeV is studied with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 35 inverse nanobarns is analyzed.The jet transverse momentum spectra are studied in seven pseudorapidity intervals covering the range -2.0 <eta[CM]< 1.5 in the NN center-of-mass frame. The jet production yields at forward and backward pseudorapidity are compared and no significant asymmetry about eta[CM] = 0 is observed in the measured kinematic range. The measurements in the pPb system are compared to reference jet spectra obtained by extrapolation from previous measurements in pp collisions at sqrt(s)=7 TeV. In all pseudorapidity ranges, nuclear modifications in inclusive jet production are found to be small, similar to the predictions from next-to-leading order perturbative QCD calculations that incorporate nuclear effects in the parton distribution functions.
