摘要
基于轻夸克和在里面中等的 Goldstonebosons 的充分处理的限制夸克增殖者，介子腐烂常数 f_ π，本地夸克真空冷凝物，和群众被调查。介子腐烂常数 f_ π被预言并且与它试验性的测量的价值相比。一个大协议被获得。与预言的 f_ π和价值 ofGoldstone，波色子群众在免费配置由实验测量了轻夸克的当前的群众和在里面中等的 Goldstone 波色子的群众被获得。
Based on the fully dressed confining quark propagator, the pion decay constant fπ, local quark vacuum condensate, and the masses of light quarks and in-medlum Goldstone bosons are investigated. The pion decay constant fπ is predicted and compared with its value of experimental measurement. A great agreement is obtained. With the predicted fπ and values of Goldstone boson masses measured by experiments in free configuration the current masses of light quarks and the masses of in-medium Goldstone bosons are obtained.
