Nucleon isovector couplings from 2+1 flavor lattice QCD at the physical point

Natsuki Tsukamoto, Yasumichi Aoki, Ken-Ichi Ishikawa +4

We present results on the axial, scalar and tensor isovector-couplings of the nucleon from 2+1 flavor lattice QCD with physical light quarks ($m_{\pi }$ = 135 MeV) in large spatial volu…
