Abstract

We present progress results from the Fastsum collaboration’s programme to determine the spectrum of the bottomonium system as a function of temperature using a variety of approaches. Inthese proceedings, the Maximum Likelihood approach is used with an Ansatz comprising of a Gaussian spectral functio...
