Description
The Phase-II upgrade of the ATLAS Tile Calorimeter (TileCal) is designed to maintain detector performance under High-Luminosity Large Hadron Collider (HL-LHC) conditions, where up to 200 proton–proton interactions per bunch crossing are expected. This study evaluates the impact of the upgraded detector geometry on jet reconstruction performance using Monte Carlo simulated QCD dijet samples. Jet transverse momentum ($p_T$) response and resolution are analysed for both the current and upgraded geometries in the high-energy regime ($1500 < p_T < 2500~GeV$). The response is defined as the mean of the $p_T/p_T^{\text{truth}}$ distribution obtained from Gaussian fits, while the resolution is defined as the ratio of the standard deviation to the mean of the same distribution. The performance is further studied as a function of the fractional energy deposition in different TileCal layers.
