ON ONE PARAMETRIZATION OF KOBAYASHI-MASKAWA MATRIX

Creators

Description

An analysis of Wolfenstein approximation to the Kobayashi-Maskawa unitary matrix shows that it has a serious flaw: it depends on three independent parameters instead of four as it should be. Because this approximation is currently used in phenomenological analyses from the quark sector, the reliability of many phenomenological results is called in question. Such an example is the PDG fit, [1], page 150, for the Kobayashi-Maskawa matrix moduli. The parametrization cannot be fixed since even when it is brought to an exact form it has the same flaw and its use leads to many inconsistencies.
