| Outline of Final Research Achievements |
Simulating finite temperature lattice QCD at temperatures higher than 165MeV, we have found a strong suppression of the topological excitation or the effect of the axial U(1) anomaly. We computed the axial U(1) susceptibility as well as meson/baryon two point correlation functions and found a good consistency with the disappearance of the axial U(1) anomaly in the chiral limit. This results were published in Physical Review D and we recieved the HPCI Excellent Achievement Award in 2020. Also, we achieved a clean separation of the chiral susceptibility into the axial U(1) breaking contributions from others and found the effect of the anomaly dominates the signal by 90%.
