Evaluation of pixel sensors produced with a commercial 150nm CMOS process for the CMS Phase-2 Upgrade / Thierry Guillaume Harte
The CMS experiment will undergo a major upgrade to prepare for the High-Luminosity phase of the LHC. Within the context of this upgrade, studies on a novel passive sensor production technique for hybrid pixel detectors were performed. The sensors were produced using a commercial CMOS process with a feature size of $150~\mathrm{nm}$ that enables the use of stitching to produce large sensors out of different sub-reticles of $11.5 \times 9.6~\mathrm{mm}^2$. [...]

CMS Phase-2 Inner Tracker system tests / Lukashenko, Valeriia (Zurich U.)
The LHC will undergo an upgrade known as the High Luminosity LHC (HL-LHC), with the aim of delivering 3000 fb$^{-1}$. The Compact Muon Solenoid (CMS) detector will be upgraded during the Phase-2 upgrade to profit from the increased luminosity delivered by HL-LHC.As a part of the Phase-2 upgrade, the CMS tracking detector will be replaced.

iRPC FEB cooling system / Kemularia, Otari (GTU, Tbilisi) /CMS Collaboration
In view of the High-Luminosity upgrade of LHC, the CMS Muon spectrometer is undergoing a series of upgrade projects,in particular the addition of four new stations featuring improved Resistive Plate Chambers (iRPC), which will cover the pseudo-rapidity range from 1.8 to 2.4. A new Front-End Board (FEB) is designed to read iRPC signals with a very low threshold and a Time Digital Converter (TDC) embedded into a Cyclone V INTEL FPGA with a resolution of 30\,ps and a sampling of 100 MHz. [...]

Design and construction of the Outer Tracker for the Phase-2 Upgrade / Zoi, Irene (Fermilab)
The High Luminosity LHC (HL-LHC) is expected to deliver an integrated luminosity of $3000-4000$~fb$^{-1}$ after 10 years of operation with peak instantaneous luminosities reaching about $5-7.5\times10^{34}$cm$^{-2}$s$^{-1}$. During Long Shutdown 3, several components of the CMS detector will undergo major changes, called the Phase-2 upgrade, to be able to operate in the challenging environment of the HL-LHC. [...]

Anomaly detection for data quality monitoring of the Muon system at CMS / Buonsante, Marco (INFN, Bari ; Bari U.) /CMS Collaboration
Ensuring the quality of data in large HEP experiments, such as CMS at the LHC is crucial for producing reliable physics outcomes. The CMS protocols for Data Quality Monitoring (DQM) are based on the analysis of a standardized set of histograms offering a condensed snapshot of the detector's condition. [...]

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. [...]
