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…
CPT transformation properties of the exact effective Hamiltonian for neutral kaon and similar complexes
K. Urbanowski
CPT-symmetry properties of the exact effective Hamiltonian H(eff) governing the time evolution in the K(0), K(O)-bar (neutral K mesons) subspace implied by such properties of the t…
