Query: A novel analysis method for excited states in lattice QCD - the nucleon
  case   We employ a novel method to analyze Euclidean correlation functions entering
the calculation of hadron energies in lattice QCD. The method is based on the
sampling of all possible solutions allowed by the spectral decomposition of the
hadron correlators. We demonstrate the applicability of the method by studying
the nucleon excited states in the positive and negative parity channels over a
pion mass range of about 400~MeV to 150~MeV. The results are compared to the
standard variational approach routinely used to study excited states within
lattice QCD. The main advantage of our new approach is its ability to
unambiguously determine all excited states for which the Euclidean time
correlation function is sensitive on.
