Description

We discuss the possibility of obtaining the spin-dependent forces between heavy quarks from a lattice Monte Carlo computation. The quantities to be measured are various combinations of Wilson loops with two plaquette insertions. We present a Monte Carlo computation with the U(1) gauge group that reproduces well the perturbative results for the spin-orbit and spin-spin interactions, and suggests that an accurate SU(3) calculation is indeed feasible and meaningful.
