The observation of $D^0 - \bar D^0$ oscillations has left us in a tantalizing quandary concerning the theoretical interpretation: are they still compatible with the SM or might they require new dynamics (NP)? A comprehensive search for CP…
The recently obtained strong evidence for $D^0 - \bar D^0$ oscillations from the $B$ factories provides an important benchmark in our search for New Physics in charm transitions. While the theoretical verdict on the observed values of $x_D$…
$D^0$ oscillations, for which the $B$ factories have found strong evidence, provide a new stage for our search for New Physics in heavy flavour dynamics. While the theoretical verdict on the observed values of $x_D$ and $y_D$ is ambiguous…
In this talk I would like to discuss two aspects of charm physics. One is to show that many standard model predictions for rare decay modes (along with $D^0 -\bar{D}^0$ mixing and CP violation) are extremely small thus opening a window for…
Charm physics has played all along a central role in particle physics, however the level of attention on it has tremendously increased in the last years because of the observation of "fast" $D^0-\bar{D}^0$ flavour oscillations and because…
The possibility of using charm meson physics to test the Standard Model (SM) is reviewed. In the case of $D^0-\bar{D}^0$ mixing, the SM contributions are carefully considered and the existence of a window for the observation of new physics…

We review recent developments in charm physics, focusing on the physics of charmed mesons. We discuss charm spectroscopy, decay constants, as well as searches for new physics with charmed mesons. We discuss D0-anti-D0 mixing and…
A biased review of recent results in charm physics is presented. New results on D0 anti-D0 mixing, rare decays of D0 and D+/-, scalar resonances in D+ and Ds decays, and new decay modes and mass measurements in Lambda_c, Xi_c, Omega_c, and…
A list is given of those open questions concerning the dynamics of charm decays where there exists a strong need for an answer. Such a need is based on lessons to be learnt about QCD -- either in their own right or for a better…
The possibility of using the charm system to search for new physics is addressed. Phenomena such as $D^0-\bar D^0$ mixing and rare decays of charmed mesons are first examined in the Standard Model to test our present understanding and to…
New results from charm experiments have led to renewed interest in this physics. The charm sector is now seen as a powerful tool to search for new physics and to advance our understanding of the standard model. We owe much of this progress…
After sketching heavy quark expansions as applied to heavy flavour decays I emphasize the relevance of nonperturbative dynamics at the charm scale for exclusive $b\to c$ modes. I address the issue of quark-hadron duality for charm and…
Detailed studies of weak charm decays fill an important {\em future} role in high energy physics. Chief among them are: (i) validating the theoretical control achieved over hadronization as a worthwhile goal in its own right; (ii)…
The motivation most often cited in searches for D0-anti-D0 mixing and CP-violation in charm system lies with the possibility of observing a signal from New Physics which dominates that from the Standard Model. We review recent theoretical…
The case for further dedicated studies of charm dynamics is presented as driven by three complementary motivations: core lessons on QCD and nonperturbative dynamics in general can be learnt; those can be applied with great profit in…
