CMS results on dark QCD signatures (emerging jets, semivisible jets, SUEP) / Cazzaniga, Cesare Tiziano (Zurich, ETH) /CMS Collaboration
We present recent results from the CMS experiment on searches for strongly coupled dark sectors using data collected during LHC Run 2. Such models can give rise to unconventional final states that may evade traditional LHC searches, including jets with unusual substructure, events with high multiplicities of soft, spherically distributed particles, or multiple displaced vertices.This report focuses on the latter two scenarios. [...]

Recent results on searches with boosted Higgs bosons at CMS / Mokhtar, Farouk (UC, San Diego) /CMS Collaboration
The study of boosted Higgs bosons at the LHC provides a unique window to probe Higgs boson couplings at high energy scales and search for signs of physics beyond the standard model. In these proceedings, we present recent results on boosted Higgs boson searches at the CMS experiment, highlighting innovative reconstruction and tagging techniques that enhance sensitivity in this challenging regime..

Heavy Ion Ultra Peripheral Collisions at CMS and ATLAS / Veres, Gabor (Eotvos U.) /ATLAS and CMS Collaborations
Recent results from the ATLAS and CMS Collaborations will be summarized, related to ultraperipheral heavy ion collisions. Those include studies of nuclear parton distributions using various final states like coherent and incoherent J/Psi, coherent Upsilon and phi, open charm, and photonuclear jets. [...]

Standard Model multibosons / Paspalaki, Garyfallia (Purdue U.) /ATLAS and CMS Collaborations
The study of multi-boson processes at the ATLAS experiments at the Large Hadron Collider (LHC) provides crucial tests of the Standard Model (SM) at the TeV scale. These measurements, including differential cross-sections and vector boson scattering (VBS), are essential for validating existing models and probing the mechanisms of electroweak symmetry breaking.

Supersymmetry searches at ATLAS and CMS / Kwon, Hyejin (Antwerp U.) /ATLAS and CMS Collaborations
This document presents recent results from the ATLAS and CMS experiments at the CERN Large Hadron Collider (LHC) on supersymmetry (SUSY) searches. These searches provide results with some non-conventional SUSY search assumptions such as with compressed mass scenario or with long-lived particle scenario. [...]

Run 3 searches with special data streams at CMS / Houghton, Connor (Rutgers U., Piscataway) /CMS Collaboration
An inclusive search for a low-mass resonance decaying to two $\tau$ leptons is presented, probing the mass range from 20 to $60~\mathrm{GeV}$ for the first time at a hadron collider. The search uses proton-proton collision data at $\sqrt{s}=13.6~\mathrm{TeV}$ corresponding to an integrated luminosity of 61.9 $\mathrm{fb}^{-1}$ collected by the CMS experiment in 2022 and 2023.

Search for Higgs boson decay to a charm quark-antiquark pair via $\mathrm{t\bar{t}H}$ production / Wuchterl, Sebastian (CERN) /CMS Collaboration
In these proceedings, a search for the standard model Higgs boson decaying to a charm quark-antiquark pair, $\mathrm{H\to c\bar{c}}$, produced in association with a top quark-antiquark pair ($\mathrm{t\bar{t}H}$) is presented. The search is performed using proton-proton collision data collected by the CMS experiment at $\sqrt{s}=13$ TeV, corresponding to an integrated luminosity of 138 fb$^{-1}$. [...]

CMS Inner Tracker Module Production and Qualification for the HL-LHC Upgrade / Amrutha Samalan of the CMS Collaboration /CMS Collaboration
The High-Luminosity Large Hadron Collider (HL-LHC) operation will push the CMS experiment to its limits with a peak instantaneous luminosity of $7.5 \times 10^{34} \text{cm}^{-2}\text{s}^{-1}$. This demanding environment will expose the CMS Inner Tracker (IT) pixel detector to unprecedented radiation levels and extreme hit rates. [...]
