Observed Quark Mixing Structure (CKM-Matrix) -- Perception of Mirror Generations

Parity nonconservation led Lee and Yang (1956) to the hypothesis of additional fermions with properties that mirror those of usual particles. It is shown here that the well-known observed qualitative structure of the quark mixing matrix (CKM matrix) is precisely reproduced when usual quark mass hierarchies result from mass hierarchies of heavy mirror generations. The last ones are of the Lee–Yang type only. The usual quark spectrum is formed likewise the see–saw spectrum of the neutrino physics. The lightest mirror quark is closely related with the t quark and might be available even in a region below 1 TeV.
