Imprint of the adjoint meson spectrum in the decay patterns of hidden-bottom tetraquarks
Sipaz Sharma, Juan Andrés Urrea-Niño, Nora Brambilla +2
We aim to clarify the experimentally observed near-degeneracy and decay patterns of the isospin, , hidden-bottom tetraquarks and with quantum numbers…
Mixing of heavy and light quarks in charmonium and light mesons
Francesco Knechtli, Jacob Finkenrath, Roman Höllwieser +3
We study the system of light mesons, charmonium and glueballs in the flavor singlet scalar channel where they can mix. We use lattice QCD simulations with an almost physical charm…
S-wave flavor-singlet meson mixing in QCD with light and charm quarks
Juan Andrés Urrea-Niño, Jacob Finkenrath, Roman Höllwieser +3
We investigate the mixing between flavor-singlet light meson and charmonium operators in the S-wave channels, i.e. pseudo-scalar and vector channel, at two different pion masses. W…
Flavor mixing in charmonium and light mesons with optimal distillation profiles
Juan Andrés Urrea-Niño, Jacob Finkenrath, Roman Höllwieser +3
We study the light meson - charmonium - glueball mixing using flavor-singlet meson operators built from optimal distillation profiles together with purely gluonic operators in diff…
Update on two-level sampling for glueball observables in quenched QCD
Lorenzo Barca, Jacob Finkenrath, Francesco Knechtli +3
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 perfo…
Static-light meson spectroscopy with optimal distillation profiles
Laura Struckmeier, Roman Höllwieser, Francesco Knechtli +3
The spectrum of static-light and static-charm mesons is studied using optimized distillation in two different QCD ensembles with pion masses of $m_π \approx 80…
Hybrid static potentials and gluelumps on ensembles
Roman Höllwieser, Francesco Knechtli, Tomasz Korzec +3
QCD permits the existence of hybrid mesons that are made up of both quarks and gluons, including exotic states, i.e., quantum numbers prohibited for pure quark-antiquark states, wi…
Exponential Error Reduction for Glueball Calculations Using a Two-Level Algorithm in Pure Gauge Theory
Lorenzo Barca, Francesco Knechtli, Sofie Martins +3
This study explores the application of a two-level algorithm to enhance the signal-to-noise ratio of glueball calculations in four-dimensional pure gauge theory. O…
The quark-mass dependence of the potential energy between static colour sources in the QCD vacuum with light and strange quarks
John Bulava, Francesco Knechtli, Vanessa Koch +2
The low-lying energy spectrum of the static-colour-source-anti-source system in a vacuum containing light and strange quarks is computed using lattice QCD for a range of different…
Charmonium spectroscopy with optimal distillation profiles
Juan Andrés Urrea-Niño, Jacob Finkenrath, Roman Höllwieser +3
We use the method of optimal distillation profiles to compute the low-lying charmonium spectrum in an ensemble at the light flavor symmetric point ($m_π \approx…
Hybrid static potentials from Laplacian Eigenmodes
Roman Höllwieser, Francesco Knechtli, Tomasz Korzec +2
We present a method for computing hybrid static quark-antiquark potentials in lattice QCD based on Laplace trial states. They are formed by eigenvector components of the covariant…
Performance of two-level sampling for the glueball spectrum in pure gauge theory
Lorenzo Barca, Francesco Knechtli, Michael Peardon +2
The computation of the glueball spectrum is particularly challenging due to the rapid decay of the signal-to-noise ratio of the correlation functions. To address this issue, advanc…
