| Description |
Assuming that the observed direct CP asymmetry in the D meson decays is mainly due to new physics, we study it in the context of Partial Compositeness. We show that, in a generic Composite Higgs model, one needs the mass of the new resonances to be at about 10 TeV. The flavor bounds in the quark sector are then easily satisfied, while there are strong tensions if one extends the construction to the lepton sector. On the other hand, embedding the picture of Partial Compositeness in Supersymmetry, one can have the superpartners around the TeV and explicitly realize the configuration called `disoriented A-terms'. It is interesting to note that in this case also the violation of lepton flavor is compatible with the experimental bounds. Moreover this can be a very motivated context for R-Parity violation. In any case, the neutron EDM is typically expected to be around the corner of the present experimental sensitivity, as well as mu to e gamma and the electron EDM.
