TL;DR
This paper demonstrates that sea quarks significantly increase the measured strong coupling constant in two-flavor full QCD compared to quenched QCD, highlighting the importance of sea quark effects in quantum chromodynamics calculations.
Contribution
It provides the first quantitative estimate of sea quark effects on the strong coupling constant at high energy scales in lattice QCD.
Findings
Sea quarks cause a 15% increase in the strong coupling constant.
Results are obtained at $eta=5.7$ with dynamical Kogut-Susskind quarks.
The study compares full QCD with quenched QCD at $ oughly$7 GeV.
Abstract
We present results showing that the strong coupling constant measured in two-flavor full QCD with dynamical Kogut-Susskind quarks at exhibit a 15\% increase due to sea quarks over that for quenched QCD at the scale GeV . (talk at lattice93)
