TL;DR
This paper investigates the bottomonium spectrum using a potential model that integrates lattice-derived gluon propagator data from SU(2) gauge theory simulations, comparing results with traditional Coulomb plus linear potentials.
Contribution
It introduces a novel potential model based on lattice SU(2) gluon propagator results for studying bottomonium, differing from conventional phenomenological potentials.
Findings
Spectrum aligns with experimental data within uncertainties
Lattice-based potential provides a viable alternative to phenomenological models
Mass of bottom quark determined as a free parameter
Abstract
We study the bottomonium spectrum using a potential model. Our potential incorporates lattice results for the gluon propagator, obtained from simulations of pure SU(2) gauge theory in Landau gauge. The mass of the bottom quark is left as a free parameter. The resulting spectrum is compared to the case of the Coulomb plus Linear (or Cornell) Potential.
