Abstract

The FASTSUM collaboration has a long-standing project examining hadronic properties usinganisotropic lattice QCD. We determine the spectral properties of bottomonia at finite temperatureusing lattice NRQCD and describe how our newer simulations improve our control over systematicerrors. Motivated by...
