The LHCb Mighty Tracker
Year: 2024
Type: conference-paper
Abstract: The Large Hadron Collider Beauty experiment (LHCb) is designed to detect decays of b- and c- hadrons for the study of flavour physics, CP violation and rare decays. The LHCb experiment will undergo its high luminosity detector upgrade in 2033-2034 to operate at a instantaneous luminosity between 1 to 1.5 $ \times 10^{34} \rm cm^{-2} s^{-1}$ . This increase in instantaneous luminosity poses a challenge to the tracking system to achieve track reconstruction with a tenfold higher occupancy. Here we focus on proposed solutions for the new tracking stations after the magnet, called Mighty-Tracker. It is of hybrid nature, comprising silicon pixels in the inner region and scintillating fibres in the outer region. The silicon pixels provide the necessary granularity and radiation tolerance to handle the high track density expected in the central region, while the scintillating fibres are well suited for the peripheral acceptance region. New R&D activities are needed in both technologies to cope with the highest instantaneous luminosity and the drastic increase in the radiation. An overview of the current status of the Mighty-Tracker project will be presented with the focus on the silicon pixels part.
