Charm Decays

I will review recent charm decay measurements from collider and fixed target experiments, with emphasis on their role in the indirect search for new physics in the flavor sector. Precision measurements of leptonic, semileptonic and hadronic charm decays improve the constraints on the Cabibbo-Kobayashi-Maskawa (CKM) quark mixing matrix, both directly through measurements of the CKM matrix elements $|V_{cd}|$ and $|V_{cs}|$ and indirectly by measuring strong interaction effects that illuminate the interpretation of CKM measurements in the b-quark sector. Rare charm decays also provide indirect constraints on new physics.
