Inclusive jet production in p+Pbp+Pb collisions at 5.02 TeV with the ATLAS detector at the LHC

Measurements of reconstructed jets in high-energy proton–lead collisions over a wide rapidity and transverse momentum range can serve as a detailed probe of the partonic structure of nuclei over a large (x,Q2)(x,Q2) range. Inclusive jet production may be sensitive to the nuclear modification of parton distribution functions and such effects as the energy loss of the initial state partons entering into the hard scattering. Furthermore, any modification of jet production in p+Pbp+Pb collisions can provide context for the strong suppression observed in central 2.76 TeV Pb+PbPb+Pb collisions which is attributed to the formation of a hot nuclear medium. We present a measurement of inclusive jet production in p+Pbp+Pb collisions with the ATLAS detector at the LHC. While the jet rate in minimum bias p+Pbp+Pb events is seen to be only slightly enhanced above the geometric expectation, the centrality-dependent yields are observed to be modified, with systematically stronger effects at higher pTpT and at more forward (proton-going) rapidities.
