Testing the SM with Charm CP Asymmetries
In order to probe for new physics in nonleptonic charm decays, we extract unknown topological amplitudes including linear SU(3)F breaking and a 1/Nc expansion from a global fit to branching ratios. Charm CP asymmetries contain even further hadronic parameters not constrained by the fit. We eliminate these in new sum rules, giving nontrivial predictions which can be used to test the Standard Model.
