Query: Recent Advances in Charm Physics   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 to the combination of precision vertexing and large data samples
collected by recent e+e- and fixed target experiments. Sensitivities to
D0-D0bar mixing and CP violation are approaching some non-standard model
predictions. Recent measurements of charmed particle lifetimes and semileptonic
decays have added to our understanding of decay mechanisms and the dynamics of
heavy-to-light quark transitions. Many of these provide vital input to QCD
models and are an essential ingredient in extracting standard model parameters
from other measurements. Studies of charmonium production continue to offer new
surprises. A recent measurement from Belle indicates that ~60% of J/psi events
produced in continuum e+e- collisions are produced with an additional charm
quark pair. Fueled by new data from a host of continuing and future
experiments, we can expect significant improvement to the standard model and
possibly some new surprises.
