TL;DR
This paper discusses the implications of a scalar glueball at approximately 1750 MeV, discovered in unquenched QCD calculations, for understanding glueball-meson mixing in the experimental scalar spectrum.
Contribution
It provides an analysis of glueball-meson mixing effects based on recent lattice QCD results and their impact on the interpretation of scalar mesons.
Findings
Confirmation of a scalar glueball at ~1750 MeV in unquenched QCD
Implications for scalar meson classification and mixing models
Insights into the scalar meson spectrum from glueball considerations
Abstract
Calculations in unquenched QCD for the scalar glueball spectrum have confirmed previous results of Gluodynamics finding a glueball at ~ 1750 MeV. I analyze the implications of this discovery from the point of view of glueball-meson mixing at the light of the experimental scalar sprectrum.
