Could Charm's "Third Time" Be the Real Charm? -- A Manifesto

Understand

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.
