SMEFT ATLAS: The Landscape Beyond the Standard Model / Aebischer, Jason (CERN) ; Buras, Andrzej J. (TUM-IAS, Munich) ; Kumar, Jacky (Los Alamos)
The Standard Model Effective Field Theory (SMEFT) based on the unbroken gauge group $\text{SU(3)}_C\otimes\text{SU(2)}_L\otimes\text{U(1)}_Y$ and containing only particles of the Standard Model (SM) has developed in the last decade to a mature field. [...]

Charged-particle production in pp collisions at 13.6 TeV and Pb-Pb collisions at 5.36 TeV with ALICE / Tripathy, Tulika (LPC, Clermont-Ferrand)
The first measurements of the charged-particle pseudorapidity density, ${\rm d}N_{\rm{ch}}/{\rm d}η$, in proton-proton (pp) collisions at $\sqrt{s} =$ 13.6 TeV and in lead-lead (Pb-Pb) collisions at $\sqrt{s_{\rm{NN}}} = $ 5.36 TeV are presented. [...]

An electron-hadron collider at the high-luminosity LHC / André, Kevin David J. (CERN) ; Holzer, Bernhard (CERN) ; Forthomme, Laurent (AGH-UST, Cracow) ; Piotrzkowski, Krzysztof (AGH-UST, Cracow)
We discuss a concept of a lower-energy version of the Large Hadron-electron Collider (LHeC), delivering electron-hadron collisions concurrently to the hadron-hadron collisions at the high-luminosity LHC at CERN. [...]

Superadditivity at Large Charge / Cohen, Timothy (CERN ; EPFL, Lausanne, LPTP ; Oregon U.) ; Fadakar, Ipak (EPFL, Lausanne, LPTP ; Pisa, Scuola Normale Superiore) ; Gomes, Andrew (EPFL, Lausanne, LPTP) ; Monin, Alexander (South Carolina U.) ; Rattazzi, Riccardo (EPFL, Lausanne, LPTP)
The weak gravity conjecture has been invoked to conjecture that the dimensions of charged operators in a CFT should obey a superadditivity relation (sometimes referred to as convexity). [...]

Challenging $\bar{B}_{(s)}\to D_{(s)}^{(*)}$ Form Factors with the Heavy Quark Expansion / Bordone, Marzia (Siegen U. ; CERN ; Zurich U.) ; Gubernari, Nico (Cambridge U.) ; Jung, Martin (Turin U.) ; van Dyk, Danny (Durham U., IPPP)
Recent publications by three lattice QCD collaborations have provided an unprecedented wealth of theoretical predictions for the $\bar{B}_q \to D_q^{(*)}$ form factors, for spectator flavours $q=u/d$ and $q=s$. [...]
