abstract

We will give results for the Upsilon spectrum on the UKQCD dynamical configurations
using clover dynamical fermions. Since these configurations are matched in lattice
spacing it is easier to search for effects of dynamical quarks than has been
true on previous dynamical ensembles.
We also extract a value for alpha_s and the b quark mass and again compare to
results on quenched ensembles.
