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 quark generations.The last ones are the Lee-Yang type only. The lightest mirror quark might be available even in a region below 1Tev.
