N2 - The energy response of the ATLAS calorimeter
is measured for single charged pions with transverse momentum 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
