Contribution

It introduces a continuum model for short-time QCD correlation functions and evaluates QCD Sum Rule techniques and nucleon interpolating fields for practical decay constant calculations.

Findings

Validated continuum model for short-time QCD correlators

Assessed effectiveness of QCD Sum Rule techniques

Discussed alternative nucleon interpolating fields

Abstract

The short-time regime of QCD two-point correlation functions is examined through a QCD-Sum-Rule-inspired continuum model. QCD Sum Rule techniques are tested and alternate nucleon interpolating fields are discussed. The techniques presented here may be of practical use in determining heavy-light meson decay constants.
