Precision tools for the simulation of double-Higgs production via vector-boson fusion / Jäger, Barbara (Tubingen U.) ; Karlberg, Alexander (CERN) ; Reinhardt, Simon (Tubingen U.)
We present two precision tools for the simulation of Higgs-pair production via vector-boson fusion in the kappa framework for the parameterization of non-standard Higgs couplings. [...]

Factorisation schemes for proton PDFs / Delorme, Stéphane (Cracow, INP) ; Kusina, Aleksander (Cracow, INP) ; Siódmok, Andrzej (Jagiellonian U.) ; Whitehead, James (Cracow, INP ; Jagiellonian U.)
Beyond leading-order, perturbative QCD requires a choice of factorisation scheme to define the parton distribution functions (PDFs) and hard-process cross-section. [...]

Accelerating Berends-Giele recursion for gluons in arbitrary dimensions over finite fields / Cruz-Martinez, Juan M. (CERN) ; De Laurentis, Giuseppe (U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Pellen, Mathieu (Freiburg U.)
This work provides a proof of concept for the computation of pure gluonic amplitudes in quantum chromodynamics (QCD) on graphics processing units (GPUs). [...]

Flavor mixing in charmonium and light mesons with optimal distillation profiles / Urrea-Niño, Juan Andrés (Wuppertal U.) ; Finkenrath, Jacob (CERN) ; Höllwieser, Roman (Wuppertal U.) ; Knechtli, Francesco (Wuppertal U.) ; Korzec, Tomasz (Wuppertal U.) ; Peardon, Michael (Trinity Coll., Dublin)
We study the light meson - charmonium - glueball mixing using flavor-singlet meson operators built from optimal distillation profiles together with purely gluonic operators in different $J^{PC}$ channels at two different pion masses ($\approx$$420$, $800$ MeV) in two $N_{\rm f} = 3 + 1$ ensembles at close to physical charm quark mass. [...]

Classical Black Hole Probes of UV Scales / Calderón-Infante, José (CERN) ; Delgado, Matilda (Garching, Max Planck Inst. ; Harvard U., Phys. Dept.) ; Li, Yixuan (Padua U. ; INFN, Padua) ; Lust, Dieter (Garching, Max Planck Inst. ; Munich U., ASC) ; Uranga, Angel M. (Madrid, IFT)
In the context of the Swampland program, black hole attractors have been employed to probe infinite distances in moduli space, where the EFT cutoff goes to zero in Planck units and UV effects become significant. [...]

On quivers, spectral networks and black holes / Arnaudo, Paolo (U. Southampton (main)) ; Grassi, Alba (U. Geneva (main) ; CERN) ; Hao, Qianyu (U. Geneva (main))
It was recently found that connection coefficients of the Heun equation can be derived in closed form using crossing symmetry in two-dimensional Liouville theory via the Nekrasov-Shatashvili functions. [...]
