Description

The response of the ATLAS hadronic Tile Calorimeter to single isolated
charged hadrons is probed analysing of LHC proton-proton collisions data
at √s = 13 TeV collected in 2017 and corresponding to an integrated
luminosity of 144.9 pb-1. The calorimeter response is determined as the
ratio of the energy deposited in the calorimeter (E) divided by the
momentum measured in the ATLAS Inner Detector (p). The average of E/p
measured in data is 0.5896 ± 0.0001 (stat), compared to an expected
value of 0.593 ± 0.001 (stat) obtained using Pythia8 simulated multijet
events. A good agreement between experimental and simulated results is
observed confirming the goodness of the calorimeter energy calibration
at the EM scale.
