2026 SciDAC PI meeting
Talks and posters from the ASCR/NP LQCD SciDAC project at the 2026 SciDAC PI meeting.
Talks
Fundamental nuclear physics at the exascale and beyond
Robert Edwards · Talk PDF
This talk surveys the SciDAC partnership's computational strategy and progress in hadron spectroscopy, including charmonium resonances, radiative decays, and three-body scattering. It connects these developments to hadron and nuclear structure and the needs of current and future experimental programs.
Scientific discoveries from RHIC to EIC through advanced computing in lattice QCD
Swagato Mukherjee · Talk PDF
This talk traces SciDAC-enabled discoveries in hot QCD matter, from the quark-gluon plasma equation of state to heavy-quark probes. It also presents advances in parton distributions, three-dimensional hadron imaging, and the quark-gluon origins of hadron mass that support the Electron-Ion Collider program.
Lattice QCD for precision and fundamental symmetry tests of the Standard Model
André Walker-Loud · Talk PDF
This talk explores how lattice QCD supports precision tests of the Standard Model and the interpretation of neutrino experiments. It discusses nucleon axial structure, two-baryon calculations, and computational strategies for reliable nuclear physics predictions.
Posters
Matrix-free gauge-equivariant neural preconditioners for the Wilson–Dirac operator
Yixuan Sun and collaborators · Poster PDF
This poster presents neural preconditioners that use gauge-field structure to accelerate lattice QCD linear solves without storing full matrices or retraining for each lattice size. It compares convergence and setup costs with existing approaches, including adaptive multigrid, and outlines further tests at larger scales.
Mapping the 3D parton structures of hadrons with lattice QCD
Jinchen He and collaborators · Poster PDF
This poster presents lattice QCD calculations of proton and pion parton distributions, including transverse-momentum distributions that reveal three-dimensional hadron structure. Using leadership-class computing and large-momentum effective theory, these results provide first-principles input for Electron-Ion Collider physics.
