Measurements of inclusive and differential Higgs boson production cross sections at $ \sqrt{s} = $ 13.6 TeV in the $ \mathrm{H}\to\gamma\gamma $ decay channel / CMS Collaboration
Inclusive and differential cross sections for Higgs boson production in proton-proton collisions at a centre-of-mass energy of 13.6 TeV are measured using data collected with the CMS detector at the LHC in 2022, corresponding to an integrated luminosity of 34.7 fb$ ^{-1} $. [...]

Long distance contributions to neutral $D$-meson mixing from lattice QCD / Di Carlo, Matteo (CERN) ; Erben, Felix (CERN) ; Hansen, Maxwell T. (Edinburgh U.)
The study of neutral $D$-meson mixing provides a unique probe of long-distance effects in the charm sector, where Standard Model contributions are dominated by nonperturbative effects. [...]

Design and construction of the Outer Tracker for the CMS Phase-2 Upgrade / Zoi, Irene (Fermilab) /CMS Collaboration
The High-Luminosity LHC (HL-LHC) is expected to deliver an integrated luminosity of 3000--4000~fb$^{-1}$ over 10 years of operation with the peak instantaneous luminosity reaching about \mbox{5--7.5$\times10^{34}$cm$^{-2}$\,s$^{-1}$}. During Long Shutdown 3, several components of the CMS detector will undergo major improvements, called Phase-2 upgrades, to be able to operate in the challenging environment of the HL-LHC. [...]

Beam test characterization of an irradiated pixel-strip module for the HL-LHC CMS tracker upgrade. / Sohail, Iqra (Quaid-i-Azam U.) /CMS Collaboration
\begin{abstract} A new tracker for the CMS detector at the Large Hadron Collider will be built to address the demands of the High Luminosity upgrade, which aims to achieve peak instantaneous luminosities from 5 up to $7.5 \times 10^{34} \, \text{cm}^{-2} \, \text{s}^{-1}$ and an integrated luminosity of 3000--4000 $ \text{fb}^{-1}$ at a center of mass energy of 14 TeV. To meet the resulting challenges, the CMS experiment is changing its outer tracker silicon modules to include tracking capabilities at the Level-1 trigger [...]
