The 2+1 flavor gauge configurations generated by the PACS-CS collaboration are used and the analysis is performed at the lightest pion mas of 156 MeV. The energy eigenstates are tracked by following the evolution of the eigenvector as the quark mass changes. The two lowest-energy odd-parity states revealed are found to be in accord with the physical N½⁻ spectrum of Nature.en© Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike LicenceConference paper002012698810.22323/1.164.01532-s2.0-8503012040420368Kamleh, W.
