Abstract: | Measurements of charged jet production as a
function of centrality are presented for p–Pb collisions
recorded at
√
sNN = 5.02TeVwith theALICEdetector.Centrality
classes are determined via the energy deposit in neutron
calorimeters at zero degree, close to the beam direction,
to minimise dynamical biases of the selection. The corresponding
number of participants or binary nucleon–nucleon
collisions is determined based on the particle production in
the Pb-going rapidity region. Jets have been reconstructed
in the central rapidity region from charged particles with
the anti-kT algorithm for resolution parameters R = 0.2 and
R = 0.4 in the transverse momentum range 20 to 120 GeV/c.
The reconstructed jet momentum and yields have been corrected
for detector effects and underlying-event background.
In the five centrality bins considered, the charged jet production
in p–Pb collisions is consistent with the production
expected from binary scaling from pp collisions. The
ratio of jet yields reconstructed with the two different resolution
parameters is also independent of the centrality selection,
demonstrating the absence of major modifications of
the radial jet structure in the reported centrality classes. |
