Description
The calculation and analysis of nucleon correlation functions is essential for understanding the observed spectra and structure of these ubiquitous hadrons. Two challenges arise in their analysis: at early Euclidean times, they are dominated by excited state contributions, and at later Euclidean times, the signal-to-noise ratio is too great to extract meaningful physics. This leads to a common challenge in identifying a reasonable window on which to extract the ground state energy. By modulating the contribution of each Laplacian eigenmode to the correlator via "distillation profiles," we build optimised operators which improve the overlap with the nucleon ground state. In this talk, we present our preliminary work on constructing these optimised distillation profiles for nucleons and their excited state suppression in two- and three-point correlation functions.
