Heavy meson description with a screened potential

We perform a quark model calculation of the bb̄ and cc̄ spectra from a screened funnel potential form suggested by unquenched lattice calculations. A connection between the lattice screening parameter and an effective gluon mass directly derived from QCD is established. Spin-spin energy splittings, leptonic widths, and radiative decays are also examined providing a test for the description of the states.
