Abstract

Charmonium (cc̄) bound states in few-nucleon systems, ²H, ⁴He and ⁸Be, are studied via Gaussian Expansion Method (GEM). We adopt a Gaussian potential as an effective (cc̄)-nucleon (N) interaction. The relation between two-body (cc̄)-N scattering length a_cc̄-N and the binding energies B of (cc̄)-nucleus bound states are given. Recent lattice QCD data of a_cc̄-N corresponds to B ≃ 0.5 MeV for (cc̄)-⁴ He and 2 MeV for (cc̄)-⁸Be in our results.
