Measurement of the hard exclusive $\pi^{0}$ muoproduction cross section at COMPASS / COMPASS Collaboration
A new and detailed measurement of the cross section for hard exclusive neutral-pion muoproduction on the proton was performed in a wide kinematic region, with the photon virtuality $Q^2$ ranging from 1 to 8 (GeV/$c$)$^{\rm\, 2}$ and the Bjorken variable $x_{\rm Bj}$ ranging from 0.02 to 0.45. [...]

Evidence for CP violation and measurement of CP-violating parameters in $ \mathrm{B}_{s}^{0} \to \mathrm{J}/\psi\,\phi(1020) $ decays in pp collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A pioneering machine-learning-based flavor-tagging algorithm combining same-side and opposite-side tagging is used to obtain the equivalent of 27 500 tagged $ \mathrm{B}_{s}^{0} \to \mathrm{J}/\psi\,\phi(1020) $ decays from pp collisions at $ \sqrt{s} = $ 13 TeV, collected by the CMS experiment and corresponding to an integrated luminosity of 96.5 fb$^{-1}$. [...]

Search for a neutral gauge boson with nonuniversal fermion couplings in vector boson fusion processes in proton-proton collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
The first search for a heavy neutral spin-1 gauge boson (Z') with nonuniversal fermion couplings produced via vector boson fusion processes and decaying to tau leptons or W bosons is presented. [...]

Identification of low-momentum muons in the CMS detector using multivariate techniques in proton-proton collisions at $ \sqrt{s} = $ 13.6 TeV / CMS Collaboration
``Soft'' muons with a transverse momentum below 10 GeV are featured in many processes studied by the CMS experiment, such as decays of heavy-flavor hadrons or rare tau lepton decays. [...]

Measurement of the W boson decay branching fraction ratio $ \mathcal{B}(\mathrm{ W \to c q })/\mathcal{B}(\mathrm{{W}\to q \bar{q}{}^{'}}) $ in proton-proton collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
The most precise measurement to date of the W boson hadronic decay branching fraction ratio $ R_\mathrm{c}^{\mathrm{W}}=\mathcal{B}(\mathrm{ W \to c q })/\mathcal{B}(\mathrm{{W}\to q \bar{q}{}^{'}}) $ is presented. [...]

Measurement of light-by-light scattering and the Breit-Wheeler process, and search for axion-like particles in ultraperipheral PbPb collisions at $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = $ 5.02 TeV / CMS Collaboration
Measurements of light-by-light scattering (LbL, $ \gamma\gamma\to\gamma\gamma $) and the Breit-Wheeler process (BW, $ \gamma\gamma\to\mathrm{e}^+\mathrm{e}^- $) are reported in ultraperipheral PbPb collisions at a centre-of-mass energy per nucleon pair of 5.02 TeV. [...]

Shielded Pair Method for Beam Screen Surface Resistance Measurement at Cryogenic Temperature / Brunner, Kristóf (CERN ; Wigner RCP, Budapest) ; Krkotić, Patrick (CERN) ; Calatroni, Sergio (CERN) ; Barna, Dániel (Wigner RCP, Budapest)
The shielded pair resonator method is a useful tool in the measurement of accelerator components, such as the beam screens used in the Large Hadron Collider (LHC), the High-Luminosity (HL) LHC, or future accelerators. It can measure the resistive losses at several frequency points by separating the resistive losses on the sample from other sources of losses. [...]
