Description
The $J/\psi J/\psi$ energy spectra are extracted from lattice QCD by utilzing the Coordinate-Space Two-Hadron Operators, named as dumbbell method.
Finite-volume energies indicate an attractive interaction in total spin $S=0$ channel and a repulsive interaction in total spin $S=1$ channel and total spin $S=2$ channel.
The scattering lengths of three different total spin are also extracted from the lattice energy levels.
