Sažetak
Composite systems with the product of mass and size close to zero are discussed from the point of view of relativistic potential models and Nambu Jona–Lasinio-like models with coherent collective states. This product is smaller than 10⁻⁶ for quarks and leptons in constituent models. It is pointed out that in potential models beside the scalar part the existence of the vector part of an effective potential is essential. The collective states require an understanding of the old problem of the meaning and the evolution of an infinite medium, the Dirac sea.
