标题： Light Quark Masses in Multi-Quark Interactions

摘要： 我们建议并详细讨论了一种多夸克三味的Nambu-Jona-Lasinio型拉格朗日量，其中包含一组与当前夸克质量成比例的有效相互作用。结果显示，在动态手征对称性破缺区域，伪戈德斯通玻色子及其手征伙伴（低能标量九重态的成员）的质量与当前现象学预期完全一致。分析了新相互作用的作用。 显示英文摘要

摘要： We suggest and discuss in detail a multi-quark three flavor Lagrangian of the Nambu -- Jona-Lasinio type, which includes a set of effective interactions proportional to the current quark masses. It is shown that within the dynamical chiral symmetry breaking regime, the masses of the pseudo Goldstone bosons and their chiral partners, members of the low lying scalar nonet, are in perfect agreement with current phenomenological expectations. The role of the new interactions is analyzed.
