Schematic SO(4) model for the description of hadrons

An algebraic model is proposed which simulates the strong interaction between quarks, for the description of hadron states. The model is based on the SO(4)-group. The effects of the long-range quark–quark interactions, like zero-color confined states, symmetries and energy dependence, required for a correct description of hadrons at low energy, are considered through the assignment of SO(4)-quantum numbers to the hadron states.
