Abstract: | The neutral kaon system is used to test the quantum theory of resonance scattering and decay phenomena. The two dimensional
Lee-Oehme-Yang theory with complex Hamiltonian is obtained by truncating the complex basis vector expansion of the exact theory
in rigged Hilbert space. This can be done forK
1 andK
2 as well as forK
S
andK
L
, depending upon whether one chooses the (self-adjoint, semibounded) Hamiltonian as commuting or noncommuting withCP. As an unexpected curiosity, one can show that the exact theory (without truncation) predicts long-time 2π decays of the
neutral kaon system even if the Hamiltonian conservesCP. |
