Highlights on Searches for Environmentally Friendly Gases in the CMS RPC System / Sandro Fonseca /CMS Collaboration
The Resistive Plate Chambers (RPC) of the Compact Muon Experiment (CMS) experiment at the Large Hadron Collider (LHC) operates with a gas mixture composed of 95.2$\%$ of C$_2$H$_2$F$_4$, a greenhouse gas with high Global-Warming Potential (GWP). In recent years, several eco-friendly alternatives, such as hydrofluoroolefins (HFOs), have been investigated to identify sustainable replacements that preserve the detector performance. [...]

Raw Data Reduction in the CMS Experiment for Run-3 and Phase-2 / Nandan, Saswati (INFN, Pisa) /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.
