Description
Recently LHCb announced the exciting discovery of direct CP asymmetry in D0 decays to K-pairs and pion pairs around 15X10^-4. It is extremely difficult to do reliable calculations for the expectations from the SM for these asymmetries because of large non-perturbative effects. However, a mechanism will be proposed to helps us understand roughly the size of the asymmetry and the key idea readily leads to several testable predictions. Moreover, even though the original amplitudes for D^0 => h^+ h^- are extremely difficult to handle on the lattice using known techniques, many features of the idea being proposed here may well be amenable to lattice simulations.
Summary
Recent LHCb discovery of direct CP asymmetry in charm decays will be discussed
