多夸克相互作用中的轻夸克质量

Light Quark Masses in Multi-Quark Interactions

A. A. Osipov, B. Hiller, A. H. Blin

摘要:

我们建议并详细讨论了Nambu-Jona-Lasinio型的多夸克三味拉格朗日量,其中包括一组与当前夸克质量成比例的有效相互作用。结果表明,在动力学手征对称性破缺机制下,赝Goldstone玻色子和它们的手征伙伴,即低位标量九重态的成员的质量与目前的唯象预期完全一致.新的相互作用的作用进行了分析。

英文摘要:

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.
