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