TL;DR
This paper uses lattice simulations to measure gauge-invariant two-point correlation functions of gauge field strengths in the QCD vacuum at very short distances, providing insights into the vacuum structure.
Contribution
It presents the first numerical determination of gauge-invariant field strength correlations in QCD at distances as short as 0.1 fm.
Findings
Correlation functions measured down to 0.1 fm
Provides data on vacuum structure at short distances
Enhances understanding of non-perturbative QCD
Abstract
We determine by numerical simulations on a lattice the gauge--invariant two--point correlation function of the gauge field strengths in the QCD vacuum, down to a distance of 0.1 fm.
