Physics Prospects, Experimental Challenges — LHCb Upgrade II

The second upgrade of the LHCb detector is planned for the long shutdown 4 of the LHC. In this upgrade, part of the existing spectrometer will be replaced and new tracking detectors allowing for time measurements will be installed. This upgrade will enable the exploitation of the physics potential of the high-luminosity LHC runs. The corresponding data sets will provide heavy-flavour results with unprecedented precision as well as significantly increase the sensitivity of BSM searches with displaced vertices. In this paper, the physics goals of Upgrade II will be reviewed, as well as the detector design and technology options which will allow for meeting the desired specifications.
