as a precision test of a new four flavor Domain Wall Fermion action
Renwick J. Hudspith, Nicolas Garron, Zack Hall +12
We present a new set of lattice QCD ensembles with four flavors of smeared Möbius Domain Wall Fermions with good chiral symmetry and small fifth-dimensional extent. A modest amoun…
Investigating the role of tetraquark operators in lattice QCD studies of the and resonances
Andrew D. Hanlon, Daniel Darvish, Sarah Skinner +7
The role of tetraquark operators in studying the isodoublet strange and isovector nonstrange scalar mesons in lattice QCD is examined using an ensemble with $m_Ï\a…
Preliminary study of the dibaryon in lattice QCD
André Baião Raposo, John Bulava, Jeremy R. Green +9
We present preliminary results on the , dibaryon in QCD. The calculation is performed with heavier-than-physical quarks ( MeV) on a…
Di-nucleons do not form bound states at heavy pion mass
John Bulava, M. A. Clark, Arjun S. Gambhir +16
We perform a high-statistics lattice QCD calculation of the low-energy two-nucleon scattering amplitudes. In order to address discrepancies in the literature, the calculation is pe…
Moments of parton distributions functions of the pion from lattice QCD using gradient flow
Anthony Francis, Patrick Fritzsch, Rohith Karur +7
We present a nonperturbative determination of the pion valence parton distribution function (PDF) moment ratios …
Using Exascale Computing to Explain the Delicate Balance of Nuclear Forces in the Universe
M. A. Clark, A. Hanlon, D. Howarth +10
The vast majority of visible matter in our universe comes from protons and neutrons (the nucleons). Nucleon interactions are fundamental to how the universe developed after the Big…
