Expected performance of the ATLAS detector at the High-Luminosity LHC
The High-Luminosity LHC (HL-LHC) will deliver proton-proton collisions at a center-of-mass energy of $\sqrt{s} = 14$ TeV with a baseline instantaneous luminosity of $5 \cdot 10^{34} \text{ cm}^{-2}\text{s}^{-1}$ and an ultimate achievable instantaneous luminosity of $7.5 \cdot 10^{34}\text{ cm}^{-2}\text{s}^{-1}$.
