Gravitational form factors of hadrons from lattice QCD
… matrix elements of the energy-momentum tensor of QCD. These quantities describe how energy, spin, and various mechanical properties of hadrons are carried by their quark and gluon constituents, and can be constrained using the framework of lattice quantum chromodynamics (QCD). In this thesis, we …

Hadronic Structure with Classical and Quantum Computing
Calculations in lattice quantum chromodynamics (QCD) — presently the only known systematically improvable approach to describe the strong nuclear force in the nonperturbative regime from first principles — are playing an increasingly important role in revealing how hadrons emerge from the …

The application of automated perturbation theory to lattice QCD
… elements must be calculated nonperturbatively. Lattice quantum chromodynamics (QCD) provides the framework for nonperturbative calculations of QCD processes. Current lattices are too coarse to directly simulate b quarks. Therefore an effective theory, nonrelativistic QCD (NRQCD), is used to …

UNRAVELING THE NUCLEON 3D STRUCTURE FROM EXPERIMENT, LATTICE, AND GLOBAL ANALYSIS
… studying the gluonic contributions to the quantum anomalous energy, mass radius, spin and mechanical pressure in the proton. We use the recent GlueX data on the $J/\psi$ photoproduction to illustrate the potential physics impact from the high-precision data from future JLab 12 GeV and EIC …

Short-distance matrix elements for D-meson mixing for 2+1 flavor lattice QCD
… mixing with partially quenched $N_f=2+1$ lattice QCD. We use a large set of the MIMD Lattice Computation Collaboration's gauge configurations with $a^2$ tadpole-improved staggered sea quarks and tadpole-improved L\""uscher-Weisz gluons. We use the $a^2$ tadpole-improved action for valence …
