On the Orthogonality of Independently Propagating States as Occurring in the Lee-Oehme-Yang Theory
G. V. Dass, W. Grimus
We generalize a theorem by Khalfin, originally derived for the states , , where is a neutral flavoured meson (e.g., or ),…
Tests of CPT invariance for neutral-flavoured-meson--antimeson mixing
G. V. Dass, W. Grimus
We focus on two aspects of CPT invariance in neutral-meson--antimeson () mixing: 1. Tests of CPT invariance, using only the property of ``lack of vacuum regeneration'…
Testing the Wigner - Weisskopf approximation by using neutral-meson - antimeson correlated states
G. V. Dass, W. Grimus
We phenomenologically decompose the Weisskopf--Wigner approximation, as applied to the neutral flavoured meson complexes, into three pieces and propose tests for these pieces. Our…
Testing CPT invariance by using C-even neutral-meson--antimeson correlated states
G. V. Dass, W. Grimus, L. Lavoura
We consider the decays of a correlated neutral-meson--antimeson state with C-parity +1. We show that there is CPT noninvariance in the mixing of the neutral mesons if, for any two…
Two-Particle Correlations and Meson-Antimeson Mixing Effects
G. V. Dass, W. Grimus
We discuss 2-particle correlations which arise in the time evolution of C-odd and C-even meson--antimeson states of flavoured neutral mesons. In order to keep our discussion genera…
Two-Particle Correlations and Mixing
G. V. Dass, K. V. L. Sarma
We study the EPR correlation implied by the entangled wavefunction of the pair created by the (4S) resonance. The analysis uses the basis provided by the mass eig…
Factorization of the charge correlation function in oscillations
G. V. Dass, K. V. L. Sarma
Extraction of the mass difference from oscillations involves tagging of bottom flavour at production and at decay. We show that the asymmetry between the unmixed…
CP-Violating Correlations between Lepton-Charge and Jet-Charge in Z -> b\bar b events
G. V. Dass, K. V. L. Sarma
Correlations that signal direct CP violation in the bottom sector are suggested. They need data on events which consist of a bottom hadron decay into an exclusive se…
The transitions and oscillations
G. V. Dass, K. V. L. Sarma
We estimate the product of the relative strength of the amplitude in the decay and the width-difference parameter . For…
Dilepton asymmetries at factories in search of transitions
G. V. Dass, K. V . L. Sarma
In order to detect the possible presence of amplitudes in neutral meson decays, we consider the measurement of decay time asymmetries involving like-sign dilepton e…
Effects of Possible Transitions in Neutral Meson Decays}
G. V. Dass, K. V. L. Sarma
We explore the possibility that the existing data on like-sign dileptons at the resonance consist of events arising from mixing and also from $ΔB =…
