Abstract
“Color confinement” of quarks is an unsolved problem in physics according to Wikipedia. This is explicitly resolved in the Scalar Strong Interaction hadron theory SSI here. Using SSI, the mass difference between charged π± and neutral π0 pions is estimated via a “marble” model to be =4.3 MeV, 6.5% off the measured 4.6 MeV, The measured charge radius rm≈0.66 fm gives a far too small classical value e2/rm≈2.2 MeV. This large mass difference is mostly tied to the strong interaction potential between the quarks in their invisible relative space of quarks. The necessary background SSI material in the Appendix includes a meson mass formula that approximately accounts for ground state meson spectra, side-stepping “lattice” calculations on computers.
