The CMS GEM alignment with a new back-propagation method
/CMS Collaboration
The next phase of high luminosity LHC (HL-LHC) foresees and increases the instantaneous luminosity in order to extend the discovery potential of the detector. In order to meet the increased particle rates and to ensure a robust and redundant system, CMS is adding new detector layers in the forward region of the muon system along with other upgrades. [...]

$\pi^{-}$ energy reconstruction in HGCAL Beam Test prototype detector using Graph Neural Networks
/CMS Collaboration
The current CMS endcap calorimeter will be replaced by a high granularity sampling calorimeter (HGCAL) for the high luminosity operation of the LHC. The HGCAL is a sampling calorimeter based on silicon sensors and scintillator tiles directly readout by SiPMs for the active media with very fine transverse and longitudinal granularity. [...]

Neural network-based algorithm for the identification of bottom quarks in the CMS Phase-2 Level-1 trigger
/CMS Collaboration
The Phase-2 upgrade of the CMS detector for the High Luminosity upgrade of the LHC (HL-LHC) includes the introduction of many new capabilities into the Level-1 trigger, including tracking and the new high- granularity calorimeter. The inclusion of tracking in particular offers the possibility of developing an algorithm to identify jets originating from bottom quarks (b-tagging) for use in the Level-1 trigger for the first time at CMS.

Performance of photon energy corrections in the CMS ECAL using graph neural networks
/CMS Collaboration
The Compact Muon Solenoid (CMS) detector is one of two general-purpose detectors on the energy frontier of particle physics at the CERN Large Hadron Collider (LHC). Products of proton-proton collisions at a center of mass energy of 13 TeV are reconstructed in the CMS detector to probe the standard model of particle physics, and to search for processes beyond the standard model.
