TL;DR
This paper investigates the running coupling constant in SU(3) pure gauge theory by analyzing the inter-quark potential from lattice simulations, providing estimates for the QCD scale parameter 55.
Contribution
It offers a detailed lattice-based determination of the running coupling and 55 scale 55 in SU(3) gauge theory, advancing non-perturbative QCD studies.
Findings
Accurate inter-quark potential measurements
Estimates of 55 and running coupling over various scales
Enhanced understanding of non-perturbative QCD dynamics
Abstract
{}From an accurate determination of the inter-quark potential, one can study the running coupling constant for a range of -values and hence estimate the scale . Detailed results are presented for pure gauge theory.
