Slides for the talk in ACAT 2019: Energy Reconstruction of the ATLAS Tile Calorimeter under high pile-up conditions using the Wiener filter

This work presents the proposed algorithm for energy estimation in the Tile Calorimeter under high pile-up conditions during LHC Run 3, named Wiener Filter. The performance of the proposed method is studied under pile-up conditions and compared with current optimal filtering method using proton-proton collision data.
