Description
In the six-quark Standard Model, flavor changing due to the weak force is described by a unitary transformation represented by the 3 × 3 matrix, known as the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The elements of this matrix, constrained theoretically by unitarity, must be determined experimentally. By investigating e+ e- collisions around the charm-quark threshold, the CLEO-c experiment has gleaned results relevant to the elements Vcs , Vcd , Vub , and Vcb from semi-leptonic, leptonic, and multi-hadronic decays of D mesons. We present these results.
