Abstract
A novel application of lattice QCD spectral reconstruction is presented, in which Euclidean correlation function data in a fixed time range are used to infer values outside the range, enabling a model-independent investigation of the asymptotic large-time behavior. Moments of the correlator are also determined, and reconstructed correlation matrices between different moments are included in a variational optimization similar to the standard Generalized Eigenvalue Problem (GEVP). These ideas are illustrated using a single-nucleon correlation function determined on an Nf = 2 + 1 ensemble of gauge configurations at mπ = 200 MeV.
