Abstract

We present results from a high precision NRQCD simulation of the quenched $\Upsilon$ system at $\beta = 6$ . We demonstrate a variety of important lattice techniques, including the perturbative improvement of actions, tadpole improvement, and multicorrelated fits for extracting the spectrum of excited states. We present new determinations of $\alpha_s(M_Z)$ and $M_b$ , two fundamental parameters of the Standard Model.
