Results of DT Longevity studies
The Drift Tube (DT) muon detector of CMS will face significant challenges as a result of the High Luminosity LHC (HL-LHC) program: it will need to function at 5 times the instantaneous luminosity that it was designed for and sustain roughly 10 times the initially expected integrated luminosity.
In order to investigate the impact of these new conditions on the detector performance, a series of accelerated irradiation tests were carried out at the CERN Gamma Irradiation Facility.
This note presents the results of longevity studies performed on one spare DT chamber after integrating approximately 50 mC/cm of charge (corresponding to 3 x HL-LHC integrated luminosity)..

Performance and quality control of the first CMS GE2/1 muon production chambers
/CMS Collaboration
The Large Hadron Collider (LHC) will soon be upgraded to prepare for the high-luminosity phase. To cope with the increase in background rates and trigger requirements, the CMS muon system is being upgraded by installing additional sets of muon detectors based on Gas Electron Multiplier (GEM) technology. [...]

CMS tracker alignment performance results for Run 3 reprocessing
/CMS Collaboration
The tracking system of the CMS experiment is the world's largest silicon tracker with its 1856 and 15148 silicon pixel and strip modules, respectively. To accurately reconstruct trajectories of charged particles the position, rotation, and curvature of each module must be corrected such that the alignment resolution is smaller than, or comparable to, the hit resolution. [...]

CMS tracker data quality certification with new machine learning tools
/CMS Collaboration
The CMS tracking system in Run 3 is made up of thousands of silicon modules. Because of the aging of the detector, and all other possible incidents that may happen during operations, there is the need for constant monitoring of the detector components, in order to guarantee the best data quality.

Run 3 detector paper L1T Plots
/CMS Collaboration
LHC Run 3 offers an opportunity to achieve significant progress in our understanding of the fundamental
nature of matter through the detection of new physics beyond the standard model, in particular by
measuring unconventional physics signatures that require the implementation of non-standard triggering
techniques. For Run 3, although no major hardware upgrade has been performed, these capabilities are
available already through the design of novel algorithm approaches, some based on machine learning (ML)
techniques. [...]
