Proton-lead measurements using the ATLAS detector

Measurements of soft and hard particle production in proton-lead collisions at the LHC have provided surprising results. Measurements of jets and high-pT hadrons have shown an unexpected enhancement in the production of high-pT charged particles and a simi- larly unexpected variation of the jet yield with proton-lead collision centrality. Studies of correlations in the production of soft particles have provided results that suggest strong collective behavior similar to that observed in lead-lead collisions. We give a brief report on the latest proton-lead measurements done by ATLAS.
