Description
The LHCb Detector, after performing beyond specification during Run 1+2 of the LHC, was successfully upgraded during Long-Shutdown 2 to the current detector, increasing the instantaneous luminosity by a factor of 5 and moving to a fully software based trigger. This will further LHCb's physics reach, enabling more world-leading measurements of CP violation, rare $b$ and $c$ hadron decays and the further discovery of new particles through spectroscopy.
LHCb Upgrade II is the planned next upgrade to be installed during LS4, allowing LHCb to operate through to the end of the LHC schedule, ramping up with the increased HL-LHC luminosity to ~40 $pp$ collisions per bunch crossing. This will provide an unprecedented and unmatched sample of $b$ and $c$ hadron decays, increasing the total luminosity yield seven-fold, with unique acceptance and a diverse physics programme. This will require a complete overhaul of the sub-detectors with time resolution, high granularity and extreme radiation hardness required to manage the increase in rate.
The motivations for LHCb Upgrade II will be presented along with an overview of the detector upgrades before focusing on the VErtex LOcator (VELO) and the recent progress on VELO Upgrade II design, simulation and ongoing R&D. Finally, the possible VELO readout methods will be discussed, with the high rates producing 20+ Tbps from the sub-detector.
