A new interpretation of one CPT violation test for K 0 âˆ’ K 0 system. Abstract Using a more accurate approximation than that applied by Leeâ€“ Oehmeâ€“Yang we show that the interpretation of the testsâ€¦ (More)

CPT transformation properties of the exact effective Hamiltonian for neutral kaon and similar complexes. Abstract CPTâ€“symmetry properties of the exact effective Hamiltonian H governing the timeâ€¦ (More)

An effect generated by the nonexponential behavior of the survival amplitude of an unstable state at the long time region is considered. It is known that this amplitude tends to zero as t goes to theâ€¦ (More)

The Lee, Oehme and Yang (LOY) theory of time evolution in two state subspace of states of the complete system is discussed. Some inconsistencies in assumptions and approximations used in the standardâ€¦ (More)

Using a more accurate effective Hamiltonian governig the time evolution in the particleâ€“antiparticle subspace of states than the one obtained within the Leeâ€“Oehmeâ€“Yang approach we show that in theâ€¦ (More)

We consider an effect generated by the nonexponential behavior of the survival amplitude of an unstable state in the long time region: In 1957 Khalfin proved that this amplitude tends to zero as tâ€¦ (More)

The Bellâ€“Steinberger relation is analyzed. The questionable points of the standard derivation of this relation are discussed. It is shown that the use of a more accurate approximation than the oneâ€¦ (More)

We begin with a discussion of the general form and general CPâ€“ and CPTâ€“ transformation properties of the Leeâ€“Oehmeâ€“Yang (LOY) effective Hamiltonian for the neutral kaon complex. Next, the propertiesâ€¦ (More)

We start from a discussion of the general form and general CPâ€“ and CPTâ€“ transformation properties of the Leeâ€“Oehmeâ€“Yang (LOY) effective Hamiltonian for the neutral kaon complex. Next we show thatâ€¦ (More)
