Numerical Evaluation of some Parameters for a Model of Neutral Kaons

Using the Mathematica program we calculate numerically the difference of the diagonal matrix elements of the time dependent effective Hamiltonian for the neutral K meson complex. We consider the exactly solvable neutral K meson model based on the one-pole approximation for the mass density. The so-called Khalfin's Theorem is numerically examined. Some characteristic parameters for this system are also calculated. The results of all calculations are presented in the graphical form. The calculations are made assuming the total system is CPT -- invariant and CP -- noninvariant.

Properties of the Effective Hamiltonian for the System of Neutral Kaons

We study the properties of time evolution of the $K^{0}-\bar{K}^{0} $ system in spectral formulation. Within the one--pole model we find the exact form of the diagonal matrix elements of the effective Hamiltonian for this system. It appears that, contrary to the Lee--Oehme--Yang (LOY) result, these exact diagonal matrix elements are different if the total system is CPT--invariant but CP--noninvariant.
