↑ and χ↓ to be large and the same, with χ=χ↑=χ↓. In this case, the model has 9
real parameters: α↑, β↑, ξ↑, η↑ for the ↑-quark sector, α↑, β↑, ξ↑, η↑
for the ↓ sector and a common χ. We examine whether these nine parameters are compatible with ten observables: the six quark masses and the four real parameters that characterize the CKM matrix (i.e., the Jarlskog invariant J and three Eulerian angles). We find that this is possible only if the T violating phase χ is large, between -120° to -135°. In this strong T violating model, the smallness of the Jarlskog invariant J≌3×10-5 is mainly accounted for by the large heavy quark masses, with mcmt smb ≈ 0.02, as well as the near complete overlap of t and b quark, with (c|b)=-0.04.
