Measurement of inclusive jet cross sections in pp and PbPb collisions at 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 CERN Large Hadron Collider, are presented. Jets are reconstructed with three different distance parameters (R = 0.2, 0.3, and 0.4) for transverse momentu...

| description | 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 CERN Large Hadron Collider, 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/c
and pseudorapidity |η| < 2. Next-to-leading-order quantum chromodynamic calculations with nonperturbative
corrections are found to overpredict 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 |
