Description:

Title: Imaging nucleon structure in lattice QCD

Speaker: Ross Young, University of Adelaide, Australia
 

Abstract: With the recent completion of the 12 GeV upgrade at Jefferson Lab, the next decade is anticipated to see tremendous advances in the understanding of nucleon and nuclear structure, with a strong emphasis on 3-dimensional imaging of quark distributions. Further beyond, the planned Electron–Ion Collider will produce detailed pictures of the corresponding gluon distributions. These experiments will be both complimented and enhanced by theoretical advances in lattice QCD. This talk will highlight recent progress in resolving the electromagnetic current distributions in the nucleon. Through development of the Feynman–Hellmann theorem to lattice QCD, I demonstrate revolutionary access to the study of high-momentum transfer processes. Correspondingly, this work has revealed dynamical features of the short-distance structure of the proton that have previously evaded calculation in nonperturbative QCD. I will conclude with an outlook to continued opportunities to engage current and future experimental programs.
