Resumen

A measurement of dijet correlations in p–Pb collisions at s_NN=5.02 TeV with the ALICE detector is presented. Jets are reconstructed from charged particles measured in the central tracking detectors and neutral energy deposited in the electromagnetic calorimeter. The transverse momentum of the full jet (clustered from charged and neutral constituents) and charged jet (clustered from charged particles only) is corrected event-by-event for the contribution of the underlying event, while corrections for underlying event fluctuations and finite detector resolution are applied on an inclusive basis. A projection of the dijet transverse momentum, k_Ty=p_T,jet ^ch+nesin(Δφ_dijet) with Δφ_dijet the azimuthal angle between a full and charged jet and p_T,jet ^ch+ne the transverse momentum of the full jet, is used to study nuclear matter effects in p–Pb collisions. This observable is sensitive to the acoplanarity of dijet production and its potential modification in p–Pb collisions with respect to pp collisions. Measurements of the dijet k_Ty as a function of the transverse momentum of the full and recoil charged jet, and the event multiplicity are presented. No significant modification of k_Ty due to nuclear matter effects in p–Pb collisions with respect to the event multiplicity or a PYTHIA8 reference is observed.
