Presented initial lattice studies of the Isgur-Wise function and $B ightarrow K^* \,\gamma$ decay.

Abstract

We report on recent developments and results from Lattice Gauge Theory. These include determinations of the strong coupling constant $\alpha_s$ and the b-quark mass $M_b$ and an update on the Kaon B parameter $B_K$. Lattice results for heavy meson decay constants and semileptonic B and D meson decay form factors are reviewed. The first attempts to study the Isgur-Wise function and the radiative Penguin decay process, $B \rightarrow K^*\,\gamma$, on the lattice are discussed.
