We consider the problem of calculating the large number of Wick contractions necessary to compute states with the quantum numbers of many baryons in lattice QCD. We consider a constructive approach and a determinant-based approach and show that these methods allow the required contractions to be performed in computationally manageable amount of time for certain choices of interpolating operators. Examples of correlation functions computed using these techniques are shown for the quantum numbers of the light nuclei, He, Be, C, O and Si.

  1. Empirical investigation of nuclear correlation function distributions in lattice QCD

    hep-lat 2025-08 conditional novelty 6.0 of 10

    The distribution of lattice QCD nuclear correlation function samples is well described by O(N) model distributions with fitted N approximately 2/B at large time separations.

  2. Spectral analysis for nucleon-pion and nucleon-pion-pion states in both parity sectors using distillation with domain-wall fermions

    hep-lat 2024-12 conditional novelty 6.0 of 10

    A distillation-based GEVP analysis resolves nucleon, nucleon-pion, and, for the first time, nucleon-pion-pion states in lattice QCD, with a physical-point nucleon mass of 0.927(21)(05) GeV.
