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…
Ground-State Extraction of Heavy-Light Meson Semileptonic Decay Form Factors
Antonino D'Anna, Alessandro Conigli, Patrick Fritzsch +7
We discuss the extraction of heavy-light pseudo-scalar to light pseudo-scalar decay form factors from finite time correlation functions. We place particular emphasis on the contami…
opbasis -- a Python package to derive minimal operator bases
Nikolai Husung
Finding a complete and yet minimal on-shell basis of operators of a given mass-dimension that are compatible with a specific set of transformation properties is the first step in a…
SymEFT for local tastes of staggered lattice QCD
Nikolai Husung
The applicability of Symanzik Effective Field Theory (SymEFT) for the description of lattice artifacts assumes a local formulation of the lattice theory. We discuss the symmetries…
Logarithmic corrections to O() effects in lattice QCD with unrooted Staggered quarks
Nikolai Husung
We derive the asymptotic lattice-spacing dependence relevant for spectral quantities of lattice QCD, when using unrooted Staggered quarks. Witho…
Lattice artifacts of local fermion bilinears up to
Nikolai Husung
Recently the asymptotic lattice spacing dependence of spectral quantities in lattice QCD has been computed to using Symanzik Effective theory [1,2]. Here, we exte…
SymEFT predictions for local fermion bilinears
Nikolai Husung
Beyond spectral quantities, Symanzik Effective Theory (SymEFT) predictions of the asymptotic lattice-spacing dependence require the inclusion of an additional minimal basis of high…
Asymptotic lattice spacing dependence of spectral quantities in lattice QCD with Wilson or Ginsparg-Wilson quarks
Nikolai Husung
One major systematic uncertainty of lattice QCD results is due to the continuum extrapolation. For an asymptotically free theory like QCD one finds corrections of the form $a^{n_\m…
Log-enhanced discretization errors in integrated correlation functions
Leonardo Chimirri, Nikolai Husung, Rainer Sommer
Integrated time-slice correlation functions with weights appear, e.g., in the moments method to determine from heavy quark correlators, in the muon g-2 determin…
Logarithmic corrections to O() and O() effects in lattice QCD with Wilson or Ginsparg-Wilson quarks
Nikolai Husung
We derive the asymptotic lattice spacing dependence relevant for spectral quantities of lattice QCD, when using Wilson, O improved Wilson o…
Logarithmic corrections to scaling in lattice QCD with Wilson and Ginsparg-Wilson quarks
Nikolai Husung, Peter Marquard, Rainer Sommer
We analyse the leading logarithmic corrections to the scaling of lattice artefacts in QCD, following the seminal work of Balog, Niedermayer and Weisz in the O(n) non-linear s…
The asymptotic approach to the continuum of lattice QCD spectral observables
Nikolai Husung, Peter Marquard, Rainer Sommer
We consider spectral quantities in lattice QCD and determine the asymptotic behavior of their discretization errors. Wilson fermion with O-improvement, (Möbius) Domain wall fe…
Asymptotic behavior of cutoff effects in Yang-Mills theory and in Wilson's lattice QCD
Nikolai Husung, Peter Marquard, Rainer Sommer
Discretization effects of lattice QCD are described by Symanzik's effective theory when the lattice spacing, , is small. Asymptotic freedom predicts that the leading asymptotic…
Logarithmic corrections to scaling in lattice Yang Mills theory
Nikolai Husung, Peter Marquard, Rainer Sommer
We analyse the leading logarithmic corrections to the scaling of lattice artefacts in QCD, following the seminal work of Balog, Niedermayer and Weisz in the O(n) non-linear s…
SU(3) Yang Mills theory at small distances and fine lattices
Nikolai Husung, Mateusz Koren, Philipp Krah +1
We investigate the SU(3) Yang Mills theory at small gradient flow time and at short distances. Lattice spacings down to fm are simulated with open boundary conditions to…
