TL;DR
The FASTSUM collaboration uses anisotropic lattice QCD to study thermal properties of hadrons, including open charm mesons, charm baryons, and bottomonium interquark potentials, providing insights into QCD at finite temperature.
Contribution
This work presents new thermal lattice QCD results on hadron spectra and interquark potentials using anisotropic lattices, advancing understanding of QCD thermodynamics.
Findings
Spectral analysis of open charm mesons and baryons at non-zero temperature.
Determination of interquark potential in bottomonium system.
Use of anisotropic lattices for improved temporal resolution.
Abstract
The FASTSUM Collaboration has developed a comprehensive research programme in thermal lattice QCD using 2+1 flavour ensembles. We review our recent hadron spectrum analyses of open charm mesons and charm baryons at non-zero temperature. We also detail our determination of the interquark potential in the bottomonium system using NRQCD quarks. All of our work uses anisotropic lattices where the temporal lattice spacing is considerably finer than the spatial one allowing better resolution of temporal correlation functions.
