Searches in the long-lived particle and dark sectors / Trocino, Daniele (INFN, Turin) /ATLAS and CMS Collaborations
Searches for dark matter (DM) and long-lived particles (LLPs) are a key focus of the ATLAS and CMS experiments at the Large Hadron Collider. Astrophysical evidence points to the existence of DM, but its nature remains elusive. [...]

Recent electroweak measurements from the CMS experiment / Alexe, Cristina-andreea (INFN, Pisa ; Pisa, Scuola Normale Superiore) /CMS Collaboration
Recent measurements of electroweak phenomena from the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider are summarized. The standard model of particle physics was tested through highly precise determinations of its key electroweak parameters and through measurements of electroweak processes in proton-proton collisions at unprecedented center-of-mass energies of up to 13.6TeV. [...]

Search for additional Higgs bosons at CMS / Gallo, Elisabetta (DESY) /CMS Collaboration
Several extensions of the standard model predict the existence of an additional Higgs doublet and therefore the existence of additional Higgs bosons. Here three searches are presented for heavy Higgs bosons decaying either into $ZZ$ and subsequently into four leptons, or into $b \bar{b}$ or $t \bar{t}$. [...]

CMS RPC non-physics event data automation ideology / Dimitrov, Anton (Sofiya U.) /CMS Collaboration
This paper presents a streamlined framework for real-time processing and analysis of condition data from the CMS experiment Resistive Plate Chambers (RPC). Leveraging data streaming, it uncovers correlations between RPC performance metrics, like currents and rates, and LHC luminosity or environmental conditions. [...]

Diffractive results from CMS / Szanyi, Istvan (EKU KRC, Gyongyos) /CMS and TOTEM Collaborations
Experimental results from the CMS and TOTEM Collaborations on diffractive processes, namely nonresonant continuum central exclusive production of pion pairs, hard color-singlet exchange in dijet events, and single-diffractive dijet production in proton-proton collisions, are presented..

Gas gaps and chambers quality control of improved resistive plate chambers (iRPC) / Ali, Mohammad Ahammad (Dundee U.) /CMS Collaboration
In preparation for the Phase-II upgrade for the High-Luminosity LHC program, 72 improved Resistive Plate Chambers (iRPC) will be installed in the third and fourth endcap disks of the Compact Muon Solenoid detector during the annual technical stop 2024. This new generation of RPC detectors will operate in a low-angle momentum (extending RPC coverage from pseudorapidity \(\lvert \eta \rvert\) = 1.9 to 2.4), in a high radiation environment, and will bring a better space and time resolution for this challenging region.

Novel ideas for CMS L1 trigger in HL-LHC using RPC ultimate timing performance / Cabrera Mora, Andres Leonardo (Andes U., Bogota) /CMS Collaboration
The CMS RPC system has been upgraded for Phase-2 with two major projects. First is the comprehensive redesign of the Link System connecting the Front-End Boards (FEBs) of existing CMS RPC chambers to the trigger processors, which leads to the full exploitation of the intrinsic time resolution of 1.6 ns.

Searches for top associated DM production at the LHC / Stafford, Dominic William (DESY) /ATLAS and CMS Collaborations
Recent searches for dark matter (DM) produced in association with top quarks from the ATLAS and CMS experiments using data collected between 2015 and 2018 are presented. These comprise searches from both experiments for DM in association with a single top quark; an improved ATLAS search for DM in single lepton $t\bar{t}$ final states; an ATLAS search stop squarks decaying to a top quark, a charm quark and neutralinos; and a CMS search for DM produced in association with a pair of top quarks or a single top.

An extension to the Analytical Method clustering algorithm for BMTL1 benefitting from CMS RPC timing / Raphael Gomes De Souza /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 early 2024). The CMS RPC system faces the challenge of the LHC expected delivered instantaneous luminosity of up to 2 x 10$^{34}$ cm$^{-2}$s$^{-1}$, providing redundant information for robust muon triggering, reconstruction and identification.
