This work was supported by JSPS Grant-in-Aid for Scientific Research (S), No. 18H0523, Japan Society for the Promotion of Science KAKENHI Grands No. JP25400244 and by Ministry of Education, Culture, Sports, Science and Technology as “Priority Issue on Post-K computer” (Elucidation of the Fundamental Laws and Evolution of the Universe) and Joint Institute for Computational Fundamental Science. We thank PACS-CS Collaboration [15] and ILDG/JLDG [20] for providing the gauge configurations. The numerical calculations have been performed on Oakforest-PACS at the University of Tokyo and OCTOPUS in Osaka University. The lattice QCD code is partly based on Bridge++ [21].

N2 - The charmonium-nucleon interaction is studied by the time-dependent HAL QCD method. We use a larger lattice volume and the relativistic heavy quark action for charm quark to obtain less systematic errors than those in our previous study. As a result, the sizable J/ψN hyperfine splitting is observed, indicating that the spin-spin interaction is important to understand this system quantitatively. No J/ψN or ηcN bound state is observed below the thresholds as in the previous results.
