Charm Phenomenology for CKM Parameters

We review several key aspects of charm phenomenology which are important for the general program of determination of matrix elements of the Cabbibo-Kobayashi-Maskava (CKM) matrix. We argue that charm physics plays an important role in reducing uncertainties in non-perturbative QCD parameters whose values are required for understanding of underlying quark-level processes. We also review the curr...

Contributions of Charm Physics to CKM Parameters

Determinations of CKM matrix elements are clouded by uncertainties in nonperturbative QCD parameters that relate measurable quantities to the underlying parton-level processes. A principal goal of the CLEO-c program is to provide precision measurements in the c-quark sector that will stimulate lattice QCD theorists to calculate relevant nonperturbative QCD parameters in this sector and to valid...

Charm Lifetimes and Mixing

Abstract. A review of the latest results on charm lifetimes and D-mixing is presented. The e+e− collider experiments are now able to measure charm lifetimes quite precisely, however comparisons with the latest results from fixed-target experiments show that possible systematic effects could be evident. The new D-mixing results from the B-factories have changed the picture that is emerging. Alth...
