Constraints fromD−D¯mixing in supersymmetric left-right symmetric models Academic Article uri icon


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