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…

The structure of the lightest positive-parity charmed mesons from LQCD
Eric B. Gregory, Feng-Kun Guo, Christoph Hanhart +2
The nature of low-lying scalar and axial-vector charmed mesons has long been debated, specifically whether they are best explained as hadronic molecules or compact tetraquark syste…

Nucleon electromagnetic form factors at large momentum from Lattice QCD
S. Syritsyn, M. Engelhardt, S. Krieg +2
Proton and neutron electric and magnetic form factors are the primary characteristics of their spatial structure and have been studied extensively over the past half-century. At la…
