Electromagnetic gauge invariance, hadron interactions and the new particle

Abstract

A generalization of the KLZ Lagrangian is developed. The hadronic symmetrySU4×U1 is broken in a gauge-invariant manner and the ψ(3.105) included as the new neutral meson in the 15⊕1 multiplet. With independence of the quantum-number content we obtain\(\Gamma _{\psi \to e^ + e^ - } \)=1.27 keV. Relations between quark structure and masses are discussed.
