Findings

Large non-standard effects in D0-D0bar mixing predicted

Visible CP violation implies lower bounds for EDMs within experimental reach

Updated constraints on MSSM mass insertions from current data

Abstract

We report on a study of CP Violation in D0-D0bar mixing and Electric Dipole Moments in the framework of supersymmetric alignment models. Both classes of observables are strongly suppressed in the Standard Model and highly sensitive to new sources of flavor and CP violation that can be present in models of New Physics. Supersymmetric alignment models generically predict large non-standard effects in D0-D0bar mixing and we show that visible CP violation in D0-D0bar mixing implies lower bounds for the EDMs of hadronic systems, like the neutron EDM and the mercury EDM, in the reach of future experimental sensitivities. We also give updated constraints on the mass insertions of the Minimal Supersymmetric Standard Model using the current data on D0-D0bar mixing.
