Abstract: (Elsevier)
The consequences of the Weinberg model of CP violation in gauge theories (ref. [1]) are discussed in detail. It is shown (using the valence quark hypothesis) that the contribution of the induced superweak interaction to the experimentally measured quantities η +− and η 00 are ≈ m K 2 / m π 2 times larger than that of the direct milliweak decay K 2 0 →2 π . The correction to the relation | η +−|/| η 00 |=1 is also calculated in the model. We estimate the neutron dipole moment (D n ⋍−2.8·10 −25 e.cm. ) and note that the dipole moments of particles with strange quark constituents should be about three orders of magnitude larger ( e.g. D Λ ⋍−1.15·10 −22 e· cm . The CP violating vertex d⇌s + gluon is also discussed.- K0: NONLEPTONIC DECAY
