Upgrade of the CMS Muon System with GEM Detectors / Thakur, Shalini (Tarapaca U.) /CMS Collaboration
The CMS detector is being upgraded for the High-Luminosity LHC (HL-LHC) run to begin in 2030. As part of the upgrade, the forward muon system is being strengthened with Gas Electron Multiplier (GEM) detectors to ensure robust performance in high-luminosity and high-background conditions in the forward region of the CMS detector. [...]

Review of flavour physics at ATLAS and CMS / Lyon, Anne-Mazarine (CERN) /ATLAS and CMS Collaborations
A review of recent results in flavour physics at the ATLAS and CMS experiments is presented. These include measurements of quarkonia and charm production cross sections, the $B^0$ lifetime, and the mass splittings between excited and ground B~meson states. [...]

Search for the nonresonant production of a pair of additional Higgs bosons in the Type-X two-Higgs-doublet model in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A search is presented for the production of two additional Higgs bosons from an off-shell Z boson, where both additional particles decay to $ \tau $ lepton pairs. [...]

Search for Higgs boson decays into two neutral scalars with unequal masses in final states with b quarks and tau leptons in proton-proton collisions at $ \sqrt{s}= $ 13 TeV
A search for Higgs boson (H) decays into a pair of neutral scalars $ \phi_{1} $ and $ \phi_{2} $, with $ \phi_{2} $ heavier than $ \phi_{1} $, is performed in final states with b quarks and tau leptons. [...]

Operational performance of the CMS Strip Tracker during LHC Run 3 / Sneh Shuchi Sneh /CMS Collaboration
The CMS silicon strip tracker consists of the inner barrel (TIB), inner discs (TID), outer barrel (TOB), and end-cap (TEC) sub-detectors, providing precise measurements for charged particle trajectories up to a pseudorapidity range of $\lvert \eta \rvert < 2.5$. During Run 3 with proton-proton collisions at $\sqrt{s} = 13.6~\mathrm{TeV}$, the CMS strip tracker continues to perform exceedingly well superseding its design goals. [...]

$B_c \to \eta_c$ form factors at large recoil: SCET analysis and a three-loop consistency check / Bell, Guido (Siegen U.) ; Böer, Philipp (CERN) ; Feldmann, Thorsten (Siegen U.) ; Horstmann, Dennis (Siegen U. ; KIT, Karlsruhe) ; Shtabovenko, Vladyslav (Siegen U.)
The double-logarithmic series of non-relativistic $B_c \to η_c$ form factors at large recoil is governed by a coupled set of integral equations, reflecting an intricate interplay between arbitrarily many soft-quark and soft-gluon exchanges. [...]
