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. [...]

From scattering towards multi-hadron weak decays / Erben, Felix (CERN)
In this article I provide an overview of the current state of scattering within lattice QCD, along with ongoing projects that examine weak decays involving scattering states as either final or intermediate states. Significant progress has been made in the study of multi-hadron weak decays, opening the door for scattering calculations to make meaningful contributions to flavour physics and further establishing lattice QCD as the key non-perturbative tool for QCD predictions.

Update on two-level sampling for glueball observables in quenched QCD / Barca, Lorenzo (NIC, Zeuthen) ; Finkenrath, Jacob (CERN) ; Knechtli, Francesco (Wuppertal U.) ; Peardon, Michael J. (Trinity Coll., Dublin) ; Schaefer, Stefan (NIC, Zeuthen) ; Urrea-Niño, Juan Andrés (Wuppertal U.)
We report our progress in combining a two-level sampling algorithm with distillation techniques for calculations of disconnected diagrams in quenched QCD. The simulations are performed on a single ensemble at $\beta=6.0$ and volume $V=16^3\times 64$, and at a pion mass of $m_\pi\approx 760~\mathrm{MeV}$..
