[a] ^ Makeup inexact due to non-zero quark masses.
[b] ^ PDG reports the عامل الجودة (Γ). Here the conversion τ = ħ⁄Γ is given instead.
[c] ^تآثر قوي حالة كمومية. No definite lifetime (see قائمة الميزونات below)
[d] ^ The mass of the
K0
L and
K0
S are given as that of the
K0
. However, it is known that a difference between the masses of the
K0
L and
K0
S on the order of 2.2×10−11 MeV/c2 exists.
[e] ^قوة نووية ضعيفة حالة كمومية. Makeup is missing small CP–violating term (see قائمة الميزونات below).
