Heavy meson description with a screened potential
We perform a quark model calculation of the bb and cc 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.

We perform a quark model calculation of the b (b) over bar and c (c) over bar 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
