Description
The Tile Calorimeter (TileCal) is a crucial component of the ATLAS detector at the Large Hadron Collider (LHC), responsible for measuring the energy of strongly interacting particles (hadrons) produced in proton–proton collisions. Accurate simulation of its performance is essential for physics analyses relying on precise jet and missing transverse energy measurements. To validate the new readout and calibration systems, extensive test beam campaigns were carried out at the CERN at Super Proton Synchrotron using muon, electron, and hadron beams over a wide energy range. In this work, three spare TileCal modules were exposed to isolated hadron beams to study the calorimeter response to pions and protons with energies between 10 and 180 GeV. The results were compared to predictions from the Geant4-based ATLAS simulation used to model proton–proton collisions at the LHC. The comparison shows good agreement within uncertainties, confirming the reliability of the TileCal response modeling and providing valuable input for future calibration and simulation improvements.
