Lattice Developments and Tools

Lattice QCD is a natural theoretical tool to study the structure of hadrons with quarks and gluons as the fundamental degrees of freedom. In this proceeding, we introduce lattice QCD and show examples of commonly used software tools from USQCD (a US lattice-QCD collaboration). We highlight a few recent lattice developments that used these shared software tools, focusing on nucleon parton distributions that are most relevant to LHC physics.
