Multiclass object tagging in the CMS Phase-2 Level-1 Correlator Trigger
/CMS Collaboration
Following developments in offline jet flavour tagging, this note introduces a new machine learning (ML) based multiclass jet tagging for the Phase-2 Upgrade of the CMS Level-1 Trigger (L1T), trained on a variety of target classes. Jet tagging will take place in the Correlator subsystem of the Phase-2 L1T. [...]

Data Reduction of the strip detector of the CMS Experiment for heavy ion collisions and proton-proton collisions
/CMS Collaboration
Reducing event and data sizes is critical for experiments at the LHC, where high collision rates and increased detector granularity rapidly increase storage and processing requirements. In the CMS experiment, a recent development to address this challenge is the "Raw'" format: a new approach for recording silicon strip data in which only the reconstructed cluster's barycenter and average charge are stored, rather than the analog-to-digital converter counts from every strip. [...]

CMS Tracker Alignment Performance Results for 2024 Data Taking and Early 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 tracking performance in 2024
/CMS Collaboration
This note presents the results of comparisons between data and Monte Carlo simulated events for tracking-related reconstructed observables. The analysis is based on data collected during 13.6 TeV proton-proton collisions in 2024. [...]

Time resolution of the diamond detectors in the CMS Precision
Proton Spectrometer in 2024
/CMS Collaboration
The Precision Proton Spectrometer (PPS) is a forward-proton
spectrometer using near-beam detectors (inside Roman Pots,
RPs) located symmetrically on both sides of IP5 at a distance of
about 220 m. In addition to the tracking system, the timing
detectors measure the Time-Of-Flight (TOF) of the protons
produced in central exclusive interactions. [...]
