Lessons from BaBar and Belle measurements of D0-(D0)over-bar mixing parameters

The BaBar and Belle experiments have recently presented evidence for D-0 - (D-0) over bar mixing. We explain the following points: (i) The measurements imply width difference y similar to 0.01. In the limit of small CP violation, the CP -odd state is longer-lived; (ii) y similar to 0.01 is consistent with the Standard Model. It suggests that SU(3) breaking from phase space effects is likely to play a major role; (iii) There is no evidence for either large mass splitting or CP violation. Consequently, there is no hint for new ohysics; (iv) The stronger bounds on the mass splitting and on CP violation imply that, if squarks are observed at the LHC, it is unlikely that they will be non-degenerate.
