Charmonium-Glueball spectroscopy with improved hadron creation operators
Juan Andrés Urrea-Niño, Francesco Knechtli, Tomasz Korzec +1
Construction of creation operators which can properly sample the underlying energy eigenstates remains a fundamental first step in lattice QCD spectroscopy calculations, particular…
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…
Hybrid Charmonium at Finite Temperature
Juan Andrés Urrea-Niño, Ryan Bignell, Ruaidhrí Campion +1
Drawing upon well established zero-temperature techniques, we present, for the first time in a lattice calculation, insight into the fate of the exotic charmonium state at…
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…
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…
