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
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. [...]

Discriminating between Pseudoscalar Higgs and Toponium States at the LHC and Beyond / Djouadi, Abdelhak (Annecy, LAPP ; Granada U., Theor. Phys. Astrophys.) ; Ellis, John (King's Coll. London ; CERN) ; Quevillon, Jeremie (Annecy, LAPP)
We discuss ways to discriminate at hadron colliders between a quasi-bound toponium state and a pseudoscalar Higgs boson A, as predicted in many extensions of the Standard Model. [...]

On Determining $\alpha_s(m_Z)$ from Dijets in $e^+e^-$ Thrust / Benitez, Miguel A. (Salamanca U., IUFFyM) ; Hoang, Andre H. (Vienna U.) ; Mateu, Vicent (Salamanca U., IUFFyM) ; Stewart, Iain W. (Vienna U. ; MIT) ; Vita, Gherardo (CERN)
We update a previous N$^3$LL$^\prime$+${\cal O}(\alpha_s^3)$ determination of the strong coupling from a global fit to thrust data by including newly available perturbative ingredients, upgrading the renormalization scales to include a fully canonical scaling region, and implementing the log resummation in a way which ensures the integrated cross section is unaffected by the the leading $1/Q$ hadronization power corrections.

On the Interplay of Constraints from $B_s$, $D$, and $K$ Meson Mixing in $Z^\prime$ Models with Implications for $b\to s \nu\bar\nu$ Transitions / Buras, Andrzej J. (TUM-IAS, Munich) ; Stangl, Peter (CERN)
Within $Z^\prime$ models, neutral meson mixing severely constrains beyond the Standard Model (SM) effects in flavour changing neutral current (FCNC) processes. [...]

Towards a differential $\mathrm{t\bar{t}W}$ cross section measurement at CMS / Marckx, David (Gent U. ; Rochester U.)
Top quark pair production in association with a W boson is a rare standard model process that has proven to be an intriguing puzzle for theorists and experimentalists alike. [...]

NNLO fits of top-quark mass using total, single-differential and double-differential $t\bar{t}+X$ cross-section data / Alekhin, S. ; Garzelli, M.V. ; Mazzitelli, J. ; Moch, S.-O. ; Zenaiev, O.
We describe the fits of the top-quark mass value at NNLO using as input the double-differential distributions in rapidity and invariant mass of $t\bar{t}$ pairs obtained by the ATLAS and CMS collaborations from unfolding of their experimental data to the parton level, compared to NNLO theory predictions.

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
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. [...]

CMS RPC performance and operation in LHC Run 3 / CMS Collaboration
The CMS experiment has collected more than 180 fb$^{-1}$ of proton-proton collision data at a 13.6 TeV center-of-mass energy in Run 3 data taking (2022, 2023 and 2024). The CMS RPC system faces the challenge of the LHC delivered instantaneous luminosity of up to 2 x 10$^{34}$ cm$^{-2}$s$^{-1}$, providing redundant information for robust muon triggering, reconstruction and identification.

Azimuthal anisotropies of charged particles with high transverse momentum in Pb+Pb collisions at 5.02 TeV with the ATLAS detector at the LHC
A measurement is presented of elliptic ($v_2$) and triangular ($v_3$) azimuthal anisotropy coefficients for charged particles produced in Pb+Pb collisions at $\sqrt{s_{_\text{NN}}} = 5.02$ TeV using a data set corresponding to an integrated luminosity of $435$ $\mu b^{-1}$ collected with the ATLAS detector at the LHC in 2018.

Differential cross section measurements of top quark pair production for variables of the dineutrino system with the CMS experiment / Consuegra Rodríguez, Sandra (RWTH Aachen U.) /CMS Collaboration
Differential top quark pair cross sections are measured in the dilepton final state as a function of kinematic variables associated to the dineutrino system. The measurements are performed making use of the Run 2 dataset collected by the CMS experiment at the CERN LHC collider, corresponding to proton-proton collisions recorded at center of mass energy of 13 TeV and an integrated luminosity of 138 fb$^{-1}$.
