Heavy Flavor Weak Decays

Weak decays of heavy flavor hadrons play a special role in our understanding of physics of the Standard Model and beyond. The measured quantities, however, result from a complicated interplay of weak and strong interactions. Weak leptonic and semileptonic decays are reasonably well understood, whereas weak hadronic decays present challenges to theory. In this talk, we review the present status of exclusive weak decays of charm and bottom hadrons.
