| dc.description | The recent observation of $D^0 - \bar D^0$ oscillations has left us in a quandary concerning the theoretical interpretation: are they driven by SM forces alone or do they involve new dynamics? A comprehensive analysis of \cp symmetry in $D$ decays can probably resolve the issue. Charm studies might thus haul in their biggest prize yet: clear evidence for the intervention of New Physics. While the absolute size of \cp asymmetries will presumably be modest at best, SM contributions should be much smaller still. Thus the ratio of `signal' to `noise' -- i.e. NP over SM contributions -- might well be larger for $D$ than $B$ transitions. A typical list of promising channels is provided, most of which should be observable in a hadronic environment. Valuable lessons can be obtained by analyzing three- and four-body final states. | |
