Results of the CMS Phase-2 TEPX system tests / Lukashenko, Valeriia (Zurich U.)
The Compact Muon Solenoid (CMS) detector will undergo a major upgrade (Phase-2) to take advantage of the increased luminosity provided by the High-Luminosity LHC (HL-LHC). As part of this upgrade, the Tracker Endcap Pixel detector (TEPX) will be introduced as a subsystem of the Phase-2 Inner Tracker, extending the pseudorapidity coverage up to $\lvert \eta \rvert < 4$. [...]

Search for black holes and sphalerons using novel machine learning techniques at CMS / Vami, Tamas Almos (UC, Santa Barbara) ; Zhang, Danyi (UC, Santa Barbara) /CMS Collaboration
A comprehensive search for microscopic black holes and electroweak sphalerons is presented, using proton-proton collision data collected by the CMS detector during 2016-2018, corresponding to an integrated luminosity of $138~\mathrm{~fb}^{-1}$. A novel tool has been developed to identify collider events with distinct kinematic features, based on the phase-space distance between events. [...]

The Inner Tracker upgrade of the CMS Experiment for the HL-LHC: design and validation via system tests / Luongo, Fabio (INFN, Turin ; Turin U.) /CMS Collaboration
The CMS Collaboration is building a new Inner Tracker to fully exploit the high-luminosity upgrade of the LHC (HL-LHC), aimed at delivering by 2041 an integrated luminosity between $ \mathrm{ 3000 \, fb^{-1} } $ and $ \mathrm{ 4000 \, fb^{-1} } $, and to cope with its more challenging operating conditions, such as the unprecedented radiation damage and the average pileup up to 200. The Inner Tracker features six times the granularity of the current Pixel Tracker of CMS, with $ \mathrm{ 25 \, \mu m \times 100 \, \mu m } $ pixel cells, the support for hit rates from particles up to $ \mathrm{ 3.5 \, GHz/cm^2 } $, and an improved radiation hardness to a total ionizing dose of $ \mathrm{ 1.2 \, Grad } $ and to a $ \mathrm{ 1 \, MeV } $-neutron-equivalent fluence of $ \mathrm{ 2.3 \times 10^{16} / cm^2 } $.

The CMS High Granularity Calorimeter trigger primitives: an overview of their implementation and optimization / Manoni, Martina (Ecole Polytechnique) /CMS Collaboration
As part of its upgrade for the High-Luminosity LHC (HL-LHC), the CMS Collaboration has chosen a novel High Granularity Calorimeter (HGCAL) to replace the endcap calorimeters. The HGCAL features fine segmentation in both the transverse and longitudinal directions, resulting in approximately six million readout channels in total. [...]

Advancements in Tau Reconstruction and Identification with the CMS experiment / Mastrapasqua, Paola (Louvain U.) /CMS Collaboration
In recent years, the CMS experiment has achieved significant progress in the reconstruction and identification of hadronically decaying tau leptons, largely driven by advances in machine learning techniques. The current CMS standard employs the Hadron Plus Strips algorithm for hadronic tau reconstruction and the latest DeepTau algorithm, based on Convolutional Neural Networks, for the identification step.

CMS track reconstruction performance during Run 3 / Ruben /CMS Collaboration
The precise reconstruction of charged particle tracks is crucial for the overall performance of the CMS experiment. In this contribution, performance measurements of the track reconstruction both in simulation and data are presented, from the collisions that occurred during the last periods of the Run 3 of data taking at the LHC.

Recent measurements of top-associated cross sections in low pileup conditions in pp collisions at $\sqrt{s}=$5.02 TeV / Javier Del Riego Badas /CMS Collaboration
We present the most recent measurements of top production cross sections in proton-proton collisions at a center-of-mass (CM) energy of 5.02~TeV. The dataset used was recorded by the CMS experiment at the LHC in special runs recorded in 2017, featuring a low-pileup environment, which offers a clean setting for precise cross-section measurements.

Attaining the optimal performance of the CMS lead tungstate Electromagnetic Calorimeter in the Run3 of LHC / Rebello Teles, Patricia (Rio de Janeiro, CBPF) /CMS Collaboration
The CMS Electromagnetic Calorimeter (ECAL) plays a central role in precision measurements involving electrons, photons, and jets. During Run 3 of the LHC, increased luminosity and detector ageing posed significant challenges for maintaining optimal energy resolution and stability. [...]
