ECAL SuperClustering with Machine Learning /CMS Collaboration
In this note, we present a novel electron/photon super-clustering algorithm based on Graph Neural Networks (GNN). This new approach has much better resolution and better energy purity even at high pile-up compared to the algorithm used during Run 2..

Machine Learning for Particle Flow Reconstruction at CMS /CMS Collaboration
We provide details on the implementation of a machine-learning based particle flow algorithm for CMS. The standard particle flow algorithm reconstructs stable particles based on calorimeter clusters and tracks and is essential for physics analyses involving jets and missing transverse energy. [...]

Analytical Method (AM) for DT Trigger Primitive Generation in Phase 2. Performance results on simulation /CMS Collaboration
A full replacement of the muon trigger system in the CMS (Compact Muon Solenoid) detector is envisaged for operating at the maximum instantaneous luminosities expected in HL-LHC (High Luminosity Large Hadron Collider) of about 5-7.5x10$^{34}$cm$^{-2}$s$^{-1}$. Under this scenario, the new on detector electronics that is being designed for the DT (Drift Tubes) detector will forward all the chamber information at its maximum time resolution. [...]

GEM Muon Performance Plots for Cosmic Ray Muon Data (April 2021) and Monte Carlo Z$\rightarrow\mu\mu$ events at 13 TeV pp Collisions /CMS Collaboration
The muon system of the CMS experiment has been instrumented with two wheels of triple-GEM detectors in order to ensure redundancy in the pseudo-rapidity region 1.55-2.2 so keeping the trigger rate at an acceptable level while not compromising the CMS physics potential in Run 3 of the LHC. The station, named GE1/1, provides two additional muon hit measurements which will improve the muon tracking and triggering performance in combination with the existing CSC detectors. [...]
