Abstract
Inclusive jet production in pPb collisions at a nucleon-nucleon (NN)
center-of-mass energy of root s(NN) = 5.02 TeV is studied with the CMS
detector at the LHC. A data sample corresponding to an integrated
luminosity of 30.1 nb(-1) 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 root s = 7 TeV. In all pseudorapidity
ranges, nuclear modifications in inclusive jet production are found to
be small, as predicted by next-to-leading order perturbative QCD
calculations that incorporate nuclear effects in the parton distribution
functions.
