The standing wave model of the mesons and baryons

Only photons are needed to explain the masses of the π⁰, η, Λ, Σ⁰, Ξ⁰, Ω⁻, Λ_c⁺, Σ_c⁰, Ξ_c⁰ and Ω_c⁰ mesons and baryons with the sum of the energies contained in the frequencies of standing electromagnetic waves in a cubic black body. Only neutrinos are needed to explain the mass of the π^± mesons with the sum of the energies of standing oscillations of muon and electron neutrinos in a cubic lattice plus the energies contained in the rest masses of the neutrinos. Neutrinos and photons are needed to explain the masses of the K^± mesons. Surprisingly the mass of the μ^± mesons can also be explained without an additional assumption by the oscillation energies and rest masses of a neutrino lattice. From the difference of the masses of the π^± mesons and μ^± mesons we find that the rest mass of the muon neutrino is 47.5 meV/c². From the difference of the masses of the neutron and proton we find that the rest mass of the electron neutrino is 0.55 meV/c². The potential of the weak force between the lattice points can be determined from Born’s lattice theory. From the weak force between the lattice points follows automatically the existence of a strong force between the sides of two lattices. The strong nuclear force is the sum of the unsaturated weak forces at the sides of each lattice and is therefore about 10⁶ times stronger than the weak force.
