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. [...]

First measurements of vector boson scattering in $ \mathrm{W}^{\pm}\mathrm{W}^{\pm} $ and $ \mathrm{W}\mathrm{Z} $ production in all-leptonic final states at $ \sqrt{s} = $ 13.6 TeV
The production cross sections of $ \mathrm{W}^{\pm}\mathrm{W}^{\pm} $ and WZ boson pairs in association with two jets in proton-proton collisions are measured at $ \sqrt{s}= $ 13.6 TeV. [...]

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. [...]

A missing link: Brane networks and the Cobordism Conjecture / Dierigl, Markus (Princeton U.) ; Ruiz, Ignacio (Princeton U.)
The absence of global symmetries in a quantum gravity theory often requires the introduction of (new) symmetry-breaking defects, which appear as singular objects in the low-energy description. [...]

Gamma Factory: A New Experimental Paradigm for CERN's HL-LHC--FCC-ee Transition / Krasny, Mieczyslaw Witold (LPNHE, Paris ; CERN)
The Gamma Factory (GF) proposal \cite{Krasny:2015ffb} is motivated by the recognition of a largely untapped potential of the CERN accelerator complex to enable a new research programme at the intersection of particle, nuclear, atomic, fundamental, and applied physics. [...]
