Possibility of a Symmetric Weak Mixing and its Implications

  • A general parametrization of the symmetric KM matrix is given.The unitarity triangle is discussed,which embodies the unitarity of the symmetric KM matrix and CP violation.It is shown that the symmetric KM matrix is consistent with the directly measured values of the KM matrix elements,CP violation parameter │ε│ of K-K system,and B0d-B0d mixing parameter χ d,provided the t-quark mass is large,m t≥160GeV.If │V 12│=│V 21│is confirmed by further experiments,KM matrix will turn out to be symmetric,so that a parameter is reduced in the standard model.

      Abstract:A general parametrization of the symmetric KM matrix is given.The unitarity triangle is discussed,which embodies the unitarity of the symmetric KM matrix and CP violation.It is shown that the symmetric KM matrix is consistent with the directly measured values of the KM matrix elements,CP violation parameter │ε│ of K-K system,and B0d-B0d mixing parameter χd,provided the t-quark mass is large,mt≥160GeV.If │V12│=│V21│is confirmed by further experiments,KM matrix will turn out to be symmetric,so that a parameter is reduced in the standard model.
