Group summary: Plans for hadron spectroscopy analyses at LHCb using Run 3 data — Mikhail Mikhasenko and •Marian Stahl — Ruhr University Bochum, Bochum, Germany

The LHCb experiment has undergone a major upgrade to be able to collect data at a five-fold increased instantaneous luminosity during Runs 3 and 4 of the LHC. With the removal of the hardware trigger, the detectors are readout at the LHC collision rate of 30 MHz and the data is processed in real-time by a heterogeneous two-stage software trigger. This leads to improved efficiencies in the event reconstruction, in particular that of fully hadronic decay channels. For spectroscopy, this opens up possibilities to search for particles with low production rates, or to measure properties of known states with improved precision or in new decay modes. I will give a comprehensive overview of LHCb’s potential for spectroscopy measurements in Run 3 and highlight topics of the immediate effort within the German spectroscopy community.
