Constraints from D-(D)over-bar mixing in supersymmetric left-right symmetric models Academic Article uri icon


  • We study the constraint arising from the recently observed D-D mixing in the context of supersymmetric models with left-right symmetry. In these models, the supersymmetric contributions in the mixing amplitudes of D-D, K-K and B-B are all correlated. We compare the constraint from the D-D mixing with the K-K mixing and find that the D-D mixing constrains the maximal supersymmetric contribution to the Bs-Bs mixing amplitude. The maximal supersymmetric contribution can allow a large CP phase of Bs-Bs mixing which agrees with the recent measurement of the CP asymmetry of BsJ/ decay. 2008 The American Physical Society.
