dc.description.abstract <p>Jets are a dominant feature of high energy particle interactions and can be interpreted in terms of the fragmentation of quarks and gluons produced in a hard scattering process. Jets provide important tools for studying hot and dense Quantum Chromodynamics (QCD) matter that is created in high energy collisions of heavy nuclei. In heavy ion collisions, such as Cu+Au, large transverse momentum partons traverse the colored Quark-Gluon Plasma (QGP) medium and lose energy which modifies the jet structure relative to jets generated in the vacuum.</p> <p>Jet production in relativistic heavy ion collisions is investigated using the Cu+Au collisions at sqrt(s_{NN}) = 200 GeV. The measurements reported here utilize 200 GeV Cu+Au and p+p data recorded by the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC) in 2012 RHIC running period. Jets are reconstructed from charged particles and electromagnetic calorimeter clusters using the anti-kt algorithm with R = 0.2.</p> <p>Inclusive, centrality-dependent jet yields within absolute pseudorapidity < 0.35 and 12.0 < p_{T} < 42.0 GeV/c are presented. The jet yield in Cu+Au collisions relative to the geometric expectation is found to be suppressed by approximately a factor of two in the most central events, nearly independent of the jet p_{T}. These results are compared with theoretical calculations with implications for sensitivity to the parton energy loss models in heavy ion collisions.</p>
