Pseudoscalar mesons
[a] ^ Makeup inexact due to non-zero quark masses.
[b] ^ PDG reports the resonance width (Γ). Here the conversion τ = ħ⁄Γ is given instead.
[c] ^ Strong eigenstate. No definite lifetime (see kaon notes below)
[d] ^ The mass of the Template:Subatomic particle and Template:Subatomic particle are given as that of the Template:Subatomic particle. However, it is known that a difference between the masses of the Template:Subatomic particle and Template:Subatomic particle on the order of Template:Val exists.[10]
[e] ^ Weak eigenstate. Makeup is missing small CP–violating term (see notes on neutral kaons below).
[s] ^ The particles quark composition is in an entangled superposition. The formula given is for the quantum state.
Vector mesons
[f] ^ PDG reports the resonance width (Γ). Here the conversion τ = ħ⁄Γ is given instead.
[g] ^ The exact value depends on the method used. See the given reference for detail.
Notes on neutral kaons
There are two complications with neutral kaons:[29]
- Due to neutral kaon mixing, the Template:Subatomic particle and Template:Subatomic particle are not eigenstates of strangeness. However, they are eigenstates of the weak force, which determines how they decay, so these are the particles with definite lifetime.
- The linear combinations given in the table for the Template:Subatomic particle and Template:Subatomic particle are not exactly correct, since there is a small correction due to CP violation. See CP violation in kaons.
Note that these issues also exist in principle for other neutral flavored mesons; however, the weak eigenstates are considered separate particles only for kaons because of their dramatically different lifetimes.[29]
