Nonstandard origin of quark masses and quark CP properties

Many phenomenologically observed properties of standard physics may be naturally explained if, instead of the usual Yukawa coupling, a new neutral vector interaction is employed to distinguish quark generations. In this case the radiative hypothesis of the quark mass hierarchy results in (a) an automatically arising hierarchy of weak mixing matrix elements, (b) a fine structure of this matrix that is the difference of hierarchy steps between elements, (c) correct orders for Im/Re ratios in mixing matrix elements, i.e., the physical determination of the CP-violation scale and, (d) the absence of strong CP violation (''θ problem'') in the scheme. A scenario is suggested to allow the new interaction to dynamically develop required properties. The fourth heavy (mQ approx-gt 1 TeV) quark generation is considered to be phenomenologically useful
