Summary
From an analysis of the Dyson-Schwinger equations we find that global colorSU(3) is not a spontaneously broken symmetry in quantum chromodynamics. Hence we conclude that either color as a local symmetry remains exact or it is broken in such a manner that global color remains an exact symmetry.
Riassunto
Da un'analisi delle equazioni di Dyson-Schwinger si trova che l'SU(3) del colore globale non è una simmetria spontaneamente rotta in cromodinamica quantistica. Quindi concludiamo che il colore come simmetria locale rimane esatto o viene rotto in maniera tale che il colore globale rimane una simmetria esatta.
Резюме
Из анализа уравнений Дайсона-Швингера мы получаем, что глобальная цветнаяSU(3) не является спонтанно нарушенной симметрией в квантовой хромодинамике. Мы делаем вывод, либо цвет, как локальная симметрия, остается точным, либо нарушение происходит таким образом, что глобальный цвет остается точной симметрией.
