Non - Orthogonality of Residues in the Wigner - Weisskopf Model for Neutral K Meson Decay
نویسندگان
چکیده
We review the application of the Wigner-Weisskopf model to the two-channel decay problem for the neutral K meson system in the resolvent formalism. The residues in the pole approximation are not orthogonal, leading to additional interference terms in the K S − K L 2π channel. We show that these terms may be detectable experimentally in the beam emitted from a regenerator.

Effect of Non - Orthogonality of Residues in the Wigner - Weisskopf model on Regeneration for the Neutral K Meson system
We review the application of the Wigner-Weisskopf model to the two-channel decay problem for the neutral K meson system in the resolvent formalism. The residues in the pole approximation are not orthogonal, leading to additional interference terms in the K S − K L 2π channel. We show that these terms lead to non-trivial changes in the exit beam in comparison to the result calculated with the as...
متن کاملEffects of final state interaction in B^+_c to D^0 K^+ decay
In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+ mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...
متن کاملInclusive Decay Distributions of Coherent Two-body States
When a vector meson such as φ, J/Ψ(3S) or Υ(4S) decays to a particleantiparticle pair of neutral mesons, the time distribution of inclusive decay to a given final state is naively expected to be the incoherent sum of those of the two mesons with opposite flavors. In this paper, we show that this is in general not the case for arbitrary coherent two-body states of the mesons, and obtain conditio...
متن کاملCombination of Colour Favoured and Colour
In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...
متن کاملWeisskopf-Wigner Decay Theory for the Energy-Driven Stochastic Schrödinger Equation
We generalize the Weisskopf-Wigner theory for the line shape and transition rates of decaying states to the case of the energy-driven stochastic Schrödinger equation that has been used as a phenomenology for state vector reduction. Working to leading order in the perturbing potential inducing the decay, and assuming that the perturbing potential has vanishing matrix elements within the degenera...
