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

: Calculating the axial form factors of the nucleon, which are vital for predicting neutrino-nucleon cross-sections. The report emphasizes that as experiments move into

: Providing a theoretical "ground truth" to improve the phenomenological models currently used in neutrino event generators. 3. Strategic Importance : Calculating the axial form factors of the

The white paper outlines several primary goals for the USQCD community:

: By precisely modeling standard model interactions, the report argues that researchers can more easily identify "new physics" or non-standard neutrino interactions. 4. Impact on Future Facilities
