dc.description.abstract | Neutral pion and η meson invariant differential
yields were measured in non-single diffractive p–Pb collisions
at √sNN = 5.02 TeV with the ALICE experiment at
the CERN LHC. The analysis combines results from three
complementary photon measurements, utilizing the PHOS
and EMCal calorimeters and the Photon Conversion Method.
The invariant differential yields of π0 and η meson inclusive
production are measured near mid-rapidity in a broad
transverse momentum range of 0.3 < pT < 20 GeV/c and
0.7 < pT < 20 GeV/c, respectively. The measured η/π0
ratio increases with pT and saturates for pT > 4 GeV/c at
0.483 ± 0.015stat ± 0.015sys. A deviation from mT scaling
is observed for pT < 2 GeV/c. The measured η/π0 ratio is
consistent with previous measurements from proton-nucleus
and pp collisions over the full pT range. The measured η/π0
ratio at high pT also agrees within uncertainties with measurements
from nucleus–nucleus collisions. The π0 and η yields
in p–Pb relative to the scaled pp interpolated reference, RpPb,
are presented for 0.3 < pT < 20 GeV/c and 0.7 < pT < 20
GeV/c, respectively. The results are compared with theoretical
model calculations. The values of RpPb are consistent with
unity for transverse momenta above 2 GeV/c. These results
support the interpretation that the suppressed yield of neutral
mesons measured in Pb–Pb collisions at LHC energies is due
to parton energy loss in the hot QCD medium. | fi |
