      Novel analysis method for excited states in lattice QCD: The nucleon case 

      Alexandrou, Constantia; Leontiou, Theodoros; Papanicolas, Costas N.; Stiliaris, Efstathios (2015)
      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 ...
