Description
We present a comparison among various methods used to extract the spectral functions of S- and P-wave meson states from non-zero temperature NRQCD correlation functions using the FASTSUM anisotropic lattice: the maximum likelihood, Backus Gilbert, and machine learning approaches. We review the common features that can be extracted by all methods and compare the results for masses and widths.
