Schemes of Quark Mixings (Oscillations) and Their Mixing Matrices

Abstract

Three schemes of quark mixings (oscillations) together with their mixing matrices (analogous to Kabibbo-Kobayashi-Maskawa matrices) are considered. In these schemes quark transitions are virtual since quark masses are different. Two of them belong to the so called mass mixing schemes (mixing parameters are expressed by elements of mass matrices) and the third scheme belongs to the charge mixings one (mixing parameters are expressed through charges). For these schemes the expressions for transition probabilities between $d, s, b$ quarks are obtained. The analysis of situation with the quark mixing parameters in these schemes is fulfilled.
