Query: Measurement of inclusive jet cross sections in pp and PbPb collisions at
  sqrt(s[NN]) = 2.76 TeV   Inclusive jet spectra from pp and PbPb collisions at a nucleon-nucleon
center-of-mass energy of 2.76 TeV, collected with the CMS detector at the LHC,
are presented. Jets are reconstructed with three different distance parameters
(R = 0.2, 0.3, and 0.4) for transverse momentum (pT) greater than 70 GeV and
pseudorapidity abs(eta) < 2. Next-to-leading-order quantum chromodynamic
calculations with non-perturbative corrections are found to over-predict jet
production cross sections in pp for small distance parameters. The jet nuclear
modification factors for PbPb compared to pp collisions, show a steady decrease
from peripheral to central events, along with a weak dependence on the jet pT.
They are found to be independent of the distance parameter in the measured
kinematic range.
