Physical Society ColloquiumInterview for Faculty PositionCKM Physics at CLEO: Past, Present and FutureKarl EcklundCornellMeasurements of the CKM matrix elements |Vcb| and |Vub| are needed to test the Standard Model's description of CP violation and quark flavor mixing. Precise determinations of |Vub| and |Vcb| are needed for tests of CKM unitarity, which could reveal new physics before it is directly observed at the energy frontier. Measurements of |Vub| and |Vcb| are made using semileptonic decays of B mesons. Such measurements are currently limited by hadronic uncertainties, but progress has recently been made in using inclusive B meson decays to limit these uncertainties. I present recent measurements of |Vcb| and |Vub| at CLEO from both exclusive and inclusive techniques. I will also give expectations for CLEO-c, detailing how results in charm decays can aid interpretation of B mixing and semileptonic decay measurements.
