Khalfin's Theorem and neutral mesons subsystem
K. Urbanowski
We analyze the proof of the Khalfin Theorem for neutral meson complex. The consequences of this Theorem are discussed: using this Theorem we find, eg., that diagonal matrix element…
Unitarity and real properties of the neutral meson complex
K. Urbanowski, J. Jankiewicz;
The proof of the Khalfin Theorem for neutral meson complex is analyzed. It is shown that the unitarity of the time evolution operator for the total system under considerations assu…
Subsystem of neutral mesons beyond the Lee-Oehme-Yang approximation
K. Urbanowski
General properties of eigenvectors and eigenvalues for an effective Hamiltonian governing time evolution in a two state subspace of the state space of the total system under consid…
CPT and effective Hamiltonians for neutral kaon and similar complexes
K. Urbanowski
We begin with a discussion of the general form and general CP-- and CPT-- transformation properties of the Lee--Oehme--Yang (LOY) effective Hamiltonian for the neutral kaon complex…
A new interpretation of one CPT violation test for system
K. Urbanowski
Using a more accurate approximation than that applied by Lee--Oehme--Yang we show that the interpretation of the tests measuring the difference between the mass and the ${\…
A contribution to the discussion of the matter-antimatter asymmetry problem
K. Urbanowski
Using a more accurate effective Hamiltonian governing the time evolution in the particle-antiparticle subspace of states than the one obtained within the Lee-Oehme--Yang approach w…
