Kaon regeneration in perturbation theory

Abstract

K 0K 0 transitions in a medium followed by decay and regeneration of K 0 S -component are considered by means of perturbation theory. It is shown that in the previous calculations the problem different from regeneration is solved.

Effect of an absorbing medium on particle oscillations

“…Therefore, s ∼ . For the K 0K 0 transitions in the medium followed by decay and regeneration of the K 0 S component an identical dependence takes place [11,12]. In the potential model pot ∼ only at light absorption.…”

Effect of an absorbing medium on particle oscillations

“…Therefore, Γ s ∼ Γ. For the K 0 K0 transitions in the medium followed by decay and regeneration of the K 0 S -component an identical Γ-dependence takes plays [11,12]. In the potential model Γ pot ∼ Γ only at light absorption.…”

New model of kaon regeneration

“…In Ref. [11] an approach based on perturbation theory was proposed. Regeneration followed by the decay K 0 L → K 0 S → ππ was considered.…”
