Protons and neutrons (collectively referred to as nucleons), composed of quarks and gluons in Quantum Chromodynamics (QCD), constitute the fundamental building blocks of atomic nuclei. Many experimental searches for new physics beyond the Standard Model of particle physics involve scattering off nuclei and nucleons, making the detailed understanding of nucleon structure (including charges and form factors) a critical input for the analysis of these experiments. This talk introduces Lattice QCD, a numerical method used to simulate QCD from first principles and calculate nucleon structure. Lattice QCD efficiently leverages supercomputers, and recent advancements in high-performance computing and GPUs have driven progress in Lattice QCD research. The talk will address the computational and technical challenges in the lattice QCD study of nucleons.
