Improving hadron creation operators for charmonium, glueballs and baryons
Juan Andrés Urrea-Niño, John Bulava, Nikolai Husung +5
Constructing hadron creation operators which properly sample the finite-volume energy spectrum is a fundamental step in lattice QCD spectroscopy and scattering calculations. Operat…
Optimized meson operators for charmonium spectroscopy and mixing with glueballs
Juan Andrés Urrea-Niño, Francesco Knechtli, Tomasz Korzec +1
Optimized meson operators in the distillation framework are used to study the charmonium spectrum in two ensembles with two heavy dynamical quarks at half the physical charm quark…
Constructing static quark-anti-quark creation operators from Laplacian eigenmodes
Roman Höllwieser, Francesco Knechtli, Tomasz Korzec +2
We investigate static quark anti-quark operators based on trial states formed from eigenvectors of the covariant three-dimensional lattice Laplace operator. We test the method by c…
The static energy of a quark-antiquark pair from Laplacian eigenmodes
Roman Höllwieser, Francesco Knechtli, Mike Peardon
We test a method for computing the static quark-antiquark potential in lattice QCD, which is not based on Wilson loops, but where the trial states are formed by eigenvector compone…
Optimising creation operators for charmonium spectroscopy on the lattice
Francesco Knechtli, Tomasz Korzec, Michael Peardon +1
Smearing the bare quantum fields in lattice calculations before applying composite hadron creation operators has a long record of substantially improving overlaps onto low-lying en…
Optimizing Distillation for charmonium and glueballs
Francesco Knechtli, Tomasz Korzec, Mike Peardon +1
We study the charmonium spectrum on an ensemble with two heavy dynamical quarks with a mass at half the physical charm quark mass. Operators for different quantum numbers are used…
