Zhang, W., Zhang arXiv: 1812.07638 ยท 2019-02-25 ## TL;DR This paper explores the expanded opportunities for flavour physics research at the HL-LHC and HE-LHC, emphasizing the importance of upgrades to LHCb, ATLAS, and CMS for discovering new physics beyond the Standard Model. ## Contribution It provides a detailed assessment of the physics potential of the HL/HE-LHC upgrades, highlighting the role of upgraded experiments in exploring new physics and their complementarity with other LHC studies. ## Key findings - Enhanced flavour physics potential with HL/HE-LHC upgrades - Synergy between flavour physics and high-$p_T$ searches for new particles - Necessity of full exploitation of flavour physics in future LHC runs ## Abstract Motivated by the success of the flavour physics programme carried out over the last decade at the Large Hadron Collider (LHC), we characterize in detail the physics potential of its High-Luminosity and High-Energy upgrades in this domain of physics. We document the extraordinary breadth of the HL/HE-LHC programme enabled by a putative Upgrade II of the dedicated flavour physics experiment LHCb and the evolution of the established flavour physics role of the ATLAS and CMS general purpose experiments. We connect the dedicated flavour physics programme to studies of the top quark, Higgs boson, and direct high-$p_T$ searches for new particles and force carriers. We discuss the complementarity of their discovery potential for physics beyond the Standard Model, affirming the necessity to fully exploit the LHC's flavour physics potential throughout its upgrade eras. ## Figures 40 figures with captions in the complete paper: https://tomesphere.com/paper/1812.07638/full.md --- Source: https://tomesphere.com/paper/1812.07638
