Time Evolution

The time evolution of an arbitrary neutral kaon state after solving eq. 2 is given by:

with

where and are the eigenvalues of the matrix . The eigenvectors which follow an exponential decay law are given by:

 

with arbitrary phases , and

In the special case of initial pure or at time we obtain:

In the limit of small violation, i.e. and small violation, i.e. , we obtain:

with and describing and violation in the mass and decay matrix:

The phase of the parameter is identical to the superweak phase . The masses and decay widths of the two eigenstates are given by gif:

In the limit of conservation and by fixing the arbitrary phase , and become eigenstates with eigenvalues +1 and -1:
