Topcolor and the First Muon Collider (Talk presented at the Workshop on Physics at the First Muon Collider and at the Front End of the Muon Collider, Nov. 1997)

We describe a class of models of electroweak symmetry breaking that involves strong dynamics and top quark condensation. A new scheme based upon a seesaw mechanism appears particularly promising. Various implications for the first-stage muon collider are discussed.Comment: 11 pages, no Fig

B--Physics in Hadron Colliders

The possibility of exploring the systematics of the spectroscopy, strong dynamics, and the weak and rare decay modes of b--quark systems at hadron colliders such as Fermilab, LHC and SSC, is discussed. A copious yield of $10^{10}$ detected $B$--mesons is readily accessible in a dedicated Fermilab program, and implies a vast array of accessible decay modes, including second order weak processes and $CP$--violation, which will be unavailable elsewhere until the commissioning of LHC or SSC. Kinematic and flavor tagging, utilizing the ``daughter pions'' from resonances, is expected to play a major role in semileptonic weak decay studies and the search for $CP$--violation.
