Heavy Meson Description with a Screened Potential

Abstract

We perform a quark model calculation of the bbˉb\bar{b} and ccˉc\bar{c} 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.
