A measurement of dijet correlations in p–Pb collisions at √sNN = 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, kTy = pch+ne
T,jet sin(ϕdijet) with ϕdijet the azimuthal angle between a full
and charged jet and pch+ne
T,jet 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 kTy as
a function of the transverse momentum of the full and recoil charged jet, and the event multiplicity are
presented. No significant modification of kTy due to nuclear matter effects in p–Pb collisions with respect
to the event multiplicity or a PYTHIA8 reference is observed.
