CMS RPC performance and operation in LHC Run 3 / CMS Collaboration
The CMS experiment has collected more than 180 fb$^{-1}$ of proton-proton collision data at a 13.6 TeV center-of-mass energy in Run 3 data taking (2022, 2023 and 2024). The CMS RPC system faces the challenge of the LHC delivered instantaneous luminosity of up to 2 x 10$^{34}$ cm$^{-2}$s$^{-1}$, providing redundant information for robust muon triggering, reconstruction and identification. [...]

R&D of the cluster finding algorithm for CMS iRPC detector / CMS Muon Collaboration
The Compact Muon Solenoid (CMS) experiment will undergo phase-II upgrade to enhance the capacity of detectors in the High-Luminosity Large Hadron Collider era. An important extension involves the installation of the Improved Resistive Plate Chambers (iRPC) in the most forward part of the endcap muon system. [...]

Measurement of the background in the CMS muon detector in ${p}{p}$-collisions at $\sqrt{s} = 13$ $\,\text {Te}\hspace{-.08em}\text {V}$ / CMS Muon Collaboration
The CMS detector, including its muon system, has been operating at the CERN LHC in increasingly challenging conditions for about 15 years. The muon detector was designed to provide excellent triggering and track reconstruction for muons produced in proton–proton collisons at an instantaneous luminosity ($\mathcal {L}$) of $1 \times 10^{34}$ cm$^{-2}$s$^{-1}$. [...]

Improved Resistive Plate Chambers for Phase-II upgrade of the CMS detector in LHC / Pinheiro, João Pedro Gomes (Rio de Janeiro Federal U.) ; Shah, Mehar Ali (Iberoamericana U.) ; Gouzevitch, Maxime (Lyon, IPN) /CMS Muon Collaboration
In anticipation of the High Luminosity LHC, an extensive upgrade is underway for the CMS Muon system to ensure its optimal performance in muon triggering and reconstruction. The indispensable role of Resistive Plate Chambers (RPC) as dedicated muon detectors stems from their exceptional timing resolution. [...]

Search for resonant pair production of Higgs bosons in the $ \textrm{b}\overline{\textrm{b}}\textrm{b}\overline{\textrm{b}} $ final state using large-area jets in proton-proton collisions at $ \sqrt{s} $ = 13 TeV / CMS Collaboration
A search is presented for the resonant production of a pair of standard model-like Higgs bosons using data from proton-proton collisions at a centre-of-mass energy of 13 TeV, collected by the CMS experiment at the CERN LHC in 2016-2018, corresponding to an integrated luminosity of 138 fb$ ^{-1} $. The final state consists of two b quark-antiquark pairs. [...]

CMS iRPC FEB development and validation / CMS Muon Collaboration
In view of the High Luminosity upgrade of the CERN LHC, the forward CMS Muon spectrometer will be extended with two new stations of improved Resistive Plate Chambers (iRPC) covering the pseudorapidity range from 1.8 to 2.4. Compared to the present RPC system, the gap thickness is reduced to lower the avalanche charge, and an innovative 2D strip readout geometry is proposed. [...]

Performance of new CO$_2$ based mixture in CMS Improved Resistive Plate Chambers in HL-LHC environment / Pinheiro, João Pedro Gomes (Rio de Janeiro Federal U.) ; Shah, Mehar Ali (Iberoamericana U.) ; Sánchez, Lucía Eiriz (Dundee U.) /CMS Muon Collaboration
Resistive Plate Chamber (RPCs) detectors in the Compact Muon Solenoid operate with a gas mixture composed of 95.2% of C2H2F4, which provides a high number of ion-electron pairs, 4.5% of iC4H10, which ensures the suppression of photon-feedback effects, and 0.3% of SF6, used as an electron quencher to further operate the detector in streamer-free mode. C2H2F4 is known to be a Greenhouse gas with a global warming potential (GWP) of 1430. [...]
