Summary
We employ chiral symmetry in quark and in hadron language to show why theCP-conserving KL-KS mass difference Δm LS is about one-half of the KS total decay rate Γs

The absolute square of the (wide) σ propagator in (15a) has been rationalized because Γτ≈m{τ}.
A σ(600) can be inferred from (18c) when one inputs the four fermion nonstrange scalar-meson massm σNS=2m qk form qk≈320 MeV. SeeY. Nambu andG. Jona-Lasinio:Phys. Rev.,122, 345 (1961);R.

Mixing angles ϕ in (17) relative to the quark basis are defined from mixing angles θ relative to the singlet-octetU(3) basis as ϕ=θ+tg-1√2 where tg-1√2≈54.7°. See,e.g.,M. D. Scadron:Phys. Rev. D,29, 2076 (1984) andA. Bramon andM. D. Scadron:Phys. Lett. B,234, 346 (1990) for the estimates ϕP≈41° and ϕS≈20°.
The inability to transform away the off-diagonal self-energy Σsd in the basis with strong eigenstates was discussed inR. Delbourgo andM. D. Scadron:Lett. Nuovo Cimento,44, 193 (1985) (see p. 196);A.
