Excited state spectroscopy in the Gross-Neveu model for dynamical fermions

Presenter: Julia Danzer — Karl-Franzens Universitšt Graz, Theoretische Physik

Julia Danzer, Prof. Dr. Christof Gattringer

We investigate the 1+1 dimensional Gross-Neveu model for Nf flavors using the HMC algorithm. Our goal is to improve the analysis for excited state spectroscopy based on the variational method. Using a set of point split interpolators we find stable, reliable signals for up to five states.
