Higgs and precision physics at CMS / Mondal, Spandan (Brown U.) /CMS Collaboration
Since the discovery of the Higgs boson in 2012, significant progress has been made in measuring several properties related to the Higgs boson. The large dataset available now facilitates precise measurements of the Higgs boson mass, natural width, couplings, production cross sections, and even differential and fiducial cross sections. [...]

Review of the measurements of the strong coupling constant in CMS at 13 TeV / Potrebko, Andris (Riga Tech. U.) /CMS Collaboration
The strong coupling constant is the least known of the coupling constants in the standardmodel. Nevertheless it appears in the calculations of cross sections of all the processes at the LHC. [...]

Measurement of the effective leptonic electroweak mixing angle and Drell–Yan forward-backward asymmetry using pp collisions at $\sqrt{s} = 13$ TeV / Khukhunaishvili, Aleko (Rochester U.) /CMS Collaboration
A measurement of the effective leptonic weak mixing angle $\sineff$ is presented using the forward-backward asymmetry in Drell--Yan dilepton events produced in ppcollisions at $\sqrt{s}=13$\,TeV. The data sample corresponds to 137\,fb$^{-1}$ of integrated luminosity and consists of dimuon and dielectron events, including the forward electrons reconstructed beyond the coverage of the CMS tracking detectors.

Exotic searches by CMS / Santanastasio, Francesco (INFN, Rome ; Rome U.) /CMS Collaboration
These proceedings present the results of new searches for various new physics phenomena in proton-proton collisions at $\sqrt{s}=$13 TeV and 13.6 TeV delivered by the LHC and collected with the CMS detector during Run 2 (2016-2018) and Run 3 (2022-2023), respectively. In many cases these analyses set the most stringent limits on these new physics phenomena to date..

Higgs coupling measurements (with emphasis to fermions) at ATLAS and CMS / Trevisani, Nicolo' (KIT, Karlsruhe, EKP) /ATLAS and CMS Collaborations
In the standard model of particle Physics, the Higgs boson is responsible for the electroweak spontaneous symmetry breaking. As a result, particles that interact with the Higgs boson acquire mass [...]

Differential measurement of top quark cross sections in association with a Z boson in CMS / Colombina, Federica (DESY) /CMS Collaboration
The first simultaneous measurement of the Z boson-associated top quark production cross sections, in pair ($\mathrm{t\bar{t}Z}$), or with a single top quark ($\mathrm{tZq}$ and $\mathrm{tWZ}$) is presented. The data were recorded from proton-proton collisions at a center of mass energy of 13 TeV with the CMS Experiment at CERN's Large Hadron Collider, corresponding to an integrated luminosity of 138 fb$^{-1}$.

CMS searches for exotic signatures / Tziaferi, Eirini (Athens U.) /CMS Collaboration
Although the standard model of particle physics provides a remarkably accurate description of phenomena associated with the known elementary particles and their interactions, it leaves significant problems unresolved with Dark Matter and Dark Energy constituting 95\% of our Universe. This motivates a comprehensive program of searches for beyond-the-standard model physics at high energy colliders. [...]
