The report emphasizes that as experiments move into the "precision era," the limiting factor will no longer be the number of neutrinos captured (statistical error) but the accuracy of the interaction models (systematic error). Lattice QCD provides the only first-principles method to solve these strong-force problems.

: Transitioning from single-nucleon calculations to multi-nucleon systems and light nuclei to understand "nuclear effects" that can bias experimental results. 12916x

: Accurate Lattice QCD inputs help reduce systematic uncertainties in oscillation parameters, such as the CP-violating phase, which could explain the matter-antimatter asymmetry in the universe. The report emphasizes that as experiments move into

The white paper outlines several primary goals for the USQCD community: such as the CP-violating phase

: Calculating the axial form factors of the nucleon, which are vital for predicting neutrino-nucleon cross-sections.
