Third moments of nucleon unpolarized, polarized, and transversity parton distribution functions from physical-point lattice QCD
Emilio Taggi, Michael Engelhardt, Jeremy R. Green +6
Using forward matrix elements of local leading-twist operators, we present a determination of the isovector third Mellin moments of nucleon unpolarized, polari…
Hadron spectroscopy and interactions
Jeremy R. Green
In recent years, lattice QCD calculations of hadron spectroscopy have concentrated on resonances and shallow bound states detected via poles in two- and three-hadron scattering amp…
Importance of local tetraquark operators for
Andres Stump, Jeremy R. Green
The doubly charmed tetraquark observed at LHCb has attracted considerable interest in recent years. To accurately determine its finite-volume spectrum, a variation…
Three-body study of the from lattice QCD
Herzallah Alharazin, André Baião Raposo, John Bulava +7
We discuss an ongoing first lattice study of the doubly-charmed tetraquark (3875) via a three-body approach. We investigate the system in the , sector,…
Status of two-baryon scattering in lattice QCD
Jeremy R. Green
In these proceedings, I will review lattice QCD calculations of baryon-baryon scattering, their methods, and their challenges. In the last few years, there has been a new generatio…
Distillation and position-space sampling for local multiquark interpolators
Andres Stump, Jeremy R. Green
Distillation in lattice QCD is a smearing method that uses the lowest eigenvectors of the spatial Laplacian to construct a subspace in which the Dirac operator can be fully inverte…
