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$^{-1}$. [...]

Standard Model W, Z (+jet) / Cipriani, Marco (INFN, Pisa ; Pisa U.) /ATLAS and CMS Collaborations
This document describes some recent measurements of single $W$ and $Z$ boson production, performed by the ATLAS and CMS Collaborations at the CERN Large Hadron Collider. These measurements provide stringent tests of theoretical calculations, as well as constraints on the parton distribution functions of the protons. [...]

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. [...]

Search for displaced top quark in the tracker of the CMS experiment at the LHC / Vaucelle, Paul (Strasbourg, IPHC) /CMS Collaboration
A search for a massive long-lived particle decaying to a top quark in proton-proton collisions at $\sqrt{s}$ = 13 TeV and 13.6 TeV is presented in this paper. Long-lived particles are predicted in several extensions of the Standard Model. [...]

Search for dark matter with mono-Higgs signature (YSF) / Shivani Sanjay Lomte /CMS Collaboration
The discovery of the Standard Model Higgs boson extended the possibility to search for dark matter in the mono-Higgs final state. A search for dark matter produced in association with a Higgs boson decaying to a pair of bottom quarks is presented, with final state signature of b-tagged jets recoiling against large missing transverse energy.

Search for vector-like quarks and vector-like leptons / Wang, Christina Wenlu (Fermilab) /ATLAS and CMS Collaborations
Many extensions of the Standard Model (SM) predict the existence of vector-like fermions--quarks (VLQs) and leptons (VLLs). This proceeding presents recent results from the ATLAS and CMS collaborations on searches for VLQs and VLLs using data collected at the LHC from 2016--2018 with proton-proton collisions of 13 TeV.

Study of energy-energy correlator of jets in PbPb collisions at CMS / Viinikainen, Jussi (Vanderbilt U.) /CMS Collaboration
Energy-energy correlator has the advantage of isolating physics of different angular scales, which has attracted a lot of interest recently to study it in heavy-ion environments. Any modification from proton-proton reference can reveal hints about the inner workings of the quark-gluon plasma. [...]
