Probing New Physics in B Penguins

J. L. Hewett

Constraints placed on physics beyond the Standard Model from the recent CLEO observation of the inclusive decay $B \to X_{s} γ$ are summarized. Further searches for new physics using t…

Searching for New Physics with Charm

J. L. Hewett

We consider the prospect of using the charm system as a laboratory for probing new physics. The theoretical expectations for rare charm meson decays, $D^{0} - ba r D^{0}$ mixing, and char…

Virtual Effects of Physics Beyond the Standard Model

J. L. Hewett

We examine the indirect effects of new physics on a variety of processes in the $B$ system, such as the $Z \to b b ˉ$ vertex, the decays $B \to X_{s} γ$ and $B \to X_{s} ℓ^{+} ℓ^{-}$ , a…
