abstract = {The energy response of the ATLAS calorimeter
is measured for single charged pions with transversemomentum
in the range 10 < pT < 300 GeV. The measurement is
performed using 139 fb−1 of LHC proton–proton collision
data at
√
s = 13 TeV taken in Run 2 by the ATLAS detector.
Charged pions originating from τ -lepton decays are used
to provide a sample of high-pT isolated particles, where the
composition is known, to test an energy regime that has not
previously been probed by in situ single-particle measurements.
The calorimeter response to single-pions is observed
to be overestimated by ∼2% across a large part of the pT
spectrum in the central region and underestimated by ∼4%
in the endcaps in the ATLAS simulation. The uncertainties in
the measurements are  1% for 15 < pT < 185 GeV in the
central region. To investigate the source of the discrepancies,
thewidth of the distribution of the ratio of calorimeter energy
to track momentum, the energies per layer and response in
the hadronic calorimeter are also compared between data and
simulation.},
