Book excerpt: I discuss the results on D°-{bar D}° mixing through hadronic as well as semi-leptonic charm decays, rare flavor-changing neutral currents in the charm sector and the lepton flavor violating [tau] decaying to charged lighter leptons. The results from both BABAR and Belle are presented in this review.

Book excerpt: Based on a dataset acquired by the BABAR experiment running on and near the {Upsilon}(4S) resonance from 1999-2002, an upper limit is set on the rate of D{sup 0}-{bar D}{sup 0} mixing using the decay mode D*{sup +} {yields} D{sup 0}{pi}{sup +}, followed by a semi-leptonic decay of the D{sup 0}. Results are compared to previous BABAR analysis using hadronic decays. We also set limits on the flavor-changing neutral current decays D{sup 0} {yields} e{sup +}e{sup -} ({mu}{sup +}{mu}{sup -}) and the lepton-flavor violation decays D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}}.

Book excerpt: We review the current status of flavor-changing neutral currents in the charm sector. We focus on the standard-model predictions and identify the main sources of theoretical uncertainties in both D° - {bar D}° mixing and rare charm decays. The potential of these observables for constraining short-distance physics in the standard model and its extensions is compromised by the presence of large nonperturbative effects. We examine the possible discovery windows in which short-distance physics can be tested and study the effects of various extensions of the standard model. The current experimental situation and future prospects are reviewed.

Book excerpt: We present an analysis of the decay D[sup 0] [yields] K[sup +][pi][sup -] from FOCUS. From a sample of 234 events we find a branching ratio of [Lambda](D[sup 0] [yields] K[sup +][pi][sup -])/[Lambda](D[sup 0] [yields] K[sup -][pi][sup +]) = (0.430[sub -0.061][sup +0.062] [+-] 0.031)% under the assumption of no mixing and no CP violation. We also present limits on charm mixing.

Book excerpt: We point out how, in certain models of New Physics, the same combination of couplings occurs in the amplitudes for both D°-{bar D}° mixing and the rare decays D° --> ll−. If the New Physics dominates and is responsible for the observed mixing, then a very simple correlation exists between the magnitudes of each; in fact the rates for the decay D° --> ll− are completely fixed by the mixing. Observation of D° --> l+l− in excess of the Standard Model prediction could identify New Physics contributions to D°-{bar D}° mixing.

Book excerpt: The results of searches for D°-{bar D}° mixing in the decays D° → K?−?° and D° → K+?−?+?−, using 230 fb−1 of e+e− collisions collected from the BABAR detector at the PEP-II storage ring at SLAC, are presented. The combination of results from these analyses yields a value for the time-integrated mixing rate R{sub M} = (0.020{sub -0.010}{sup +0.011}(stat.))%, and an upper limit R{sub M}
