标题： Spontaneously broken color

摘要： 量子色动力学的真空由希格斯机制表征。 颜色在八维表示中通过夸克-反夸克凝聚而被“自发破坏”。 大质量的胶子携带整数电荷，并被识别为矢量介子。 费米子激发包括低质量重子八重态和单态。 这些粒子与轻赝标八重态之间的相互作用主要由手征对称性和非线性局部对称性决定。 从一个简单的有效作用量中出现了强相互作用在长距离下的一致现象学图景。 显示英文摘要

摘要： The vacuum of QCD is characterized by the Higgs mechanism. Color is ``spontaneously broken'' by a quark-antiquark condensate in the octet representation. The massive gluons carry integer electric charges and are identified with the vector mesons. The fermionic excitations consist of the low mass baryon octet and a singlet. The interactions between these particles and the light pseudoscalar octet are largely determined by chiral symmetry and a nonlinear local symmetry. A consistent phenomenological picture of strong interactions at long distances arises from a simple effective action.
