Han and Nambu also assigned each quark color an integer electrical charge, so that the quarks were fractionally charged only on average, and they did not expect the quarks in their model to be permanently confined.
Han a Nambu tiež priradili každej farbe kvarku celočíselný elektrický náboj, takže kvarky mali zlomkový náboj iba v priemere a neočakávali, že ich model trvalo vymedzí kvarky.
