Measurement of the fractional radiation length of a pixel module for the CMS Phase-2 upgrade via the multiple scattering of positrons / Tracker Group of the CMS Collaboration
High-luminosity particle collider experiments such as the ones planned at the High-Luminosity Large Hadron Collider require ever-greater vertexing precision of the tracking detectors, necessitating also reductions in the material budget of the detectors. Traditionally, the fractional radiation length ($x/X_0$) of detectors is either estimated using known properties of the constituent materials, or measured in dedicated runs of the final detector.

Beam Test Performance Studies of CMS Phase-2 Outer Tracker Module Prototypes / Tracker Group of the CMS Collaboration
A new tracking detector will be installed as part of the Phase-2 upgrade of the CMS detector for the high-luminosity LHC era. This tracking detector includes the Inner Tracker, equipped with silicon pixel sensor modules, and the Outer Tracker, consisting of modules with two parallel stacked silicon sensors. [...]

A Geant4-based simulation study for a preliminary setup of the MUonE experiment / Asenov, Patrick (INFN, Perugia ; CNR IRPI, Perugia) ; Abbiendi, Giovanni (INFN, Bologna) ; Goncerz, Mateusz (Cracow, INP) ; Ivanchenko, Vladimir (CERN) ; Kucharczyk, Marcin (Cracow, INP) ; Loukas, Dimitrios (Democritos Nucl. Res. Ctr.) ; Marconi, Umberto (INFN, Bologna) ; Matteuzzi, Clara (INFN, Milan Bicocca) ; Zdybal, Milosz (Cracow, INP)
MUonE is a proposed experiment which aims at an independent and precise determination of the leading hadronic contribution to the muon $g-2$, based on the measurement of the hadronic running of the electromagnetic coupling in the space-like region. This can be achieved by measuring with extremely high accuracy the shape of the differential cross section of the $\mu e$ elastic scattering, using a 160$\,$GeV muon beam available at CERN, off atomic electrons of a light target.

Evaluation of planar silicon pixel sensors with the RD53A readout chip for the Phase-2 Upgrade of the CMS Inner Tracker / CMS Collaboration
The Large Hadron Collider (LHC) at CERN will undergo an upgrade in order to increase its luminosity to $7.5 \times 10^{34}$ cm$^{-2}$s$^{-1}$. The increased luminosity during this High-Luminosity running phase\\ (HL-LHC), starting around 2029, means a higher rate of proton-proton interactions, hence a larger ionizing dose and particle fluence for the detectors. The current tracking system of the CMS experiment will be fully replaced in order to cope with the new operating conditions. [...]

Evaluation of HPK $n^+$-$p$ planar pixel sensors for the CMS Phase-2 upgrade / Tracker Group of the CMS Collaboration
To cope with the challenging environment of the planned high luminosity upgrade of the Large Hadron Collider (HL-LHC), scheduled to start operation in 2029, CMS will replace its entire tracking system. The requirements for the tracker are largely determined by the long operation time of 10~years with an instantaneous peak luminosity of up to $7.5\times 10^{34}$~cm$^{-2}$s$^{-1}$ in the ultimate performance scenario. Depending on the radial distance from the interaction point, the silicon sensors will receive a particle fluence corresponding to a non-ionizing energy loss of up to $\Phi_{\text{eq}} = 3.5\times 10^{16}$~cm$^{-2}$. [...]

A search for decays of the Higgs boson to invisible particles in events with a top-antitop quark pair or a vector boson in proton-proton collisions at $\sqrt{s} = 13\,\text {Te}\hspace{-.08em}\text {V} $ / CMS Collaboration
A search for decays to invisible particles of Higgs bosons produced in association with a top-antitop quark pair or a vector boson, which both decay to a fully hadronic final state, has been performed using proton-proton collision data collected at $ \sqrt{s}= $ 13 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 138 fb$ ^{-1} $. The 95% confidence level upper limit set on the branching fraction of the 125 GeV Higgs boson to invisible particles, $ {\mathcal{B}(\mathrm{H} \to \text{inv})} $, is 0.47 (0.40 expected), assuming standard model production cross sections.

Test beam performance of a CBC3-based mini-module for the Phase-2 CMS Outer Tracker before and after neutron irradiation / Tracker Group of the CMS Collaboration
The Large Hadron Collider (LHC) at CERN will undergo major upgrades to increase the instantaneous luminosity up to 5-7.5$\times10^{34}$ cm$^{-2}$s$^{-1}$. This High Luminosity upgrade of the LHC (HL-LHC) will deliver a total of 3000-4000 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 13-14 TeV. [...]
