Abstract

We report preliminary results for charmonium-nucleon potential V ccX̄N(r) from quenched lattice QCD, which is calculated from the equal-time Bethe-Salpeter amplitude through the effective Schrödinger equation. Our simulations are performed at a lattice cutoff of 1/a=2.0GeV in a spatial volume of (3fm)3 with the nonperturbatively O(a) improved Wilson action for the light quarks and a relativistic heavy quark action for the charm quark. We have found that the potential VccX̄N(r) is weakly attractive at short distance and exponentially screened at long distance.
