Operational experience with the Silicon Strip Tracker at the CMS experiment / Shvetsov, Ivan (KIT, Karlsruhe, EKP) /CMS Collaboration
The CMS Silicon Strip Tracker with its more than 15000 silicon modules and 200 m$^2$ of active silicon area is in its tenth year of operation at the LHC. We present the performance of the detector in the LHC Run 2 data taking. [...]

Calibration and performance of the CMS pixel detector in LHC Run 2 / Vami, Tamas Almos (Johns Hopkins U.) /CMS Collaboration
The Compact Muon Solenoid (CMS) is one of two general-purpose detectors that reconstruct the products of high energy particle interactions at the Large Hadron Collider at CERN. The silicon pixel detector is the innermost component of the CMS tracking system. [...]

Relative nonlinearity of BRIL luminometers derived from CMS $\mu$ scans / Babaev, Anton (TOMSK-POLYTEC) /CMS Collaboration
The CMS Beam Radiation Instrumentation and Luminosity (BRIL) Project is devoted to the simulation and measurements of beam conditions and luminosity for CMS. One of the BRIL tasks is the luminosity monitoring and calibration of the detectors to obtain the luminosity. [...]

Rare top quark production at the LHC:\\ t$\bar{\text{t}}$Z, t$\bar{\text{t}}$W, t$\bar{\text{t}}\gamma$, tZq, t$\gamma$q, and t$\bar{\text{t}}$t$\bar{\text{t}}$ / Knolle, Joscha (DESY) /ATLAS and CMS Collaborations
A comprehensive set of measurements of top quark pair and single top quark production in association with electroweak bosons (W, Z, or $\gamma$) is presented. The results are compared to standard model (SM) predictions and used to set limits on new physics effects that would induce deviations from the SM. [...]

Electroweak measurements at the High-Luminosity LHC / Savin, Alexander (Wisconsin U., Madison) /ATLAS and CMS Collaborations
A set of selected standard model measurements proposed for the ATLAS and CMS experiments after the high-luminosity upgrade of the LHC is discussed. The measurements are separated into two categories: precise measurements that benefit from both improved systematic uncertainties and increased luminosity, like W or top mass, or weak mixing angle measurements; measurements of low cross section production that benefit mainly from luminosity increase and detector improvements, like VV VBS polarized cross section measurements or study of VVV production..

Differential measurements of Higgs production at ATLAS and CMS / Sculac, Toni (Split Tech. U.) /ATLAS and CMS Collaborations
Differential Higgs boson production cross sections are sensitive probes for physics beyond the Standard Model. New physics may contribute in the gluon-gluon fusion loop, the dominant Higgs boson production mechanism at the LHC, and manifest itself through deviations from the distributions predicted by the standard model. [...]

Results on Proton-Irradiated 3D Pixel Sensors Interconnected to RD53A Readout ASIC / Duarte Campderros, Jordi (Cantabria Inst. of Phys.) /CMS Collaboration
Test beam results obtained with 3D pixel sensors bump-bonded to the RD53A prototype readout ASIC are reported. Sensors from FBK (Italy) and IMB-CNM (Spain) have been tested before and after proton-irradiation to an equivalent fluence of about $1$ $\times$ $10^{16}$ n$_{\text{eq}}$ cm$^{-2}$ (1 MeV equivalent neutrons).

Searches for Light Higgs Bosons at the CMS Experiment / Kalogeropoulos, Alexis (Princeton U.) /CMS Collaboration
We report on recent results by the CMS Collaboration on searches for light Higgs bosons based on a sample of proton-proton collision data at $\sqrt{s} =13$ TeV, corresponding to a total integrated luminosity of 35.9 fb$^{-1}$..

Pixel detector for CMS upgrade / Orfanelli, Stella (CERN) /CMS Collaboration
The LHC machine upgrade program will increase the instantaneous luminosity delivered to the multi-purpose experiments up to 7.5x$10^{34}$\,cm$^{-2}$s$^{-1}$ in 2026, with the goal of an integrated luminosity of 3000\,fb$^{-1}$ by the end of 2037. In order to fully exploit this luminosity, CMS plans to build a completely new pixel detector. [...]
