Outline of Final Research Achievements |
Nucleon structure calculations using three 2+1-flavor domain-wall fermion lattice QCD ensembles with a lattice cutoff momentum of about 1.38GeV/c and pion mass of about 249 and 172 MeV and another cutoff momentum of about 1.73GeV/c and pion mass of almost physical 139MeV were advanced. In the former two ensembles the calculations of nucleon mass, isovector vector and axialvector charges, and isovector tensor and scalar couplings were completed and a full paper reporting these were published. Calculations of the same observables in the last ensemble progressed: for the first time in the world an influence from nucleon excited state was confirmed in the isovector vector charge. Also the calculated value of the isovector axialvector charge slightly undershoots the experimental value.
