Abstract
I review recent progress made in the calculation of nucleon structure in lattice QCD. Due to space limitations, I will focus on a few specific topics: systematic control of lattice-QCD matrix elements, probing TeV-physics with the aid of nucleon tensor and scalar charges, and Bjorken-x dependence of nucleon parton distribution functions.
Highlights
Nucleon Matrix Elements on the Lattice The nucleon is a building block of all ordinary matter, and the study of nucleon structure is a critical goal of physics
The usual recipe is to check the source-sink dependence at low statistics and identify one value for full production; it is difficult to be completely sure that the chosen value of the separation would be clean of excited-state contamination at the full statistical precision
To facilitate accurate extraction of the excited state to disentangle it from the ground state, we can either add operators that overlap differently with the Recent Progress on Nucleon Structure with Lattice QCD
Summary
Calculations on ensembles at the physical pion mass are an attainable near-term goal; they will require large-enough volumes for nucleon matrix elements and long trajectories. To facilitate accurate extraction of the excited state to disentangle it from the ground state, we can either add operators that overlap differently with the Recent Progress on Nucleon Structure with Lattice QCD
