Charmonium-nucleon interaction from lattice QCD with a relativistic heavy quark action

Understand

Detailed information of the low-energy interaction between the charmonia ({\eta}c and J/{\psi}) and the nucleon is indispensable for exploring the formation of charmonium bound to nuclei.

• In order to investigate the charmonium-nucleon interactions at low energies, we adopt two essentially different approaches in lattice QCD simulations.
• The charmonium-nucleon potential can be calculated from the equal-time Bethe-Salpeter amplitude through the effective Schr\"odinger equation.
• This novel method is based on the same idea originally applied for the nucleon force by Aoki- Hatsuda-Ishii.
