标题： On a Possible Explanation of the Origin of the Quark Mass Spectrum

摘要： 与通常情况下夸克质量谱由夸克Yukawa耦合决定，而希格斯场的真空期望值保持普遍的情况相反，我们建议考虑相反的情况。 每一代的夸克和轻子都与自己的希格斯二重态相关联，而Yukawa耦合是相同的。 这种情况在有限超对称大统一场景的框架中自然出现。 夸克质量谱的非简并性是由于不对称的真空期望值，这些期望值在希格斯领域中自发地破坏了离散的味对称性。 显示英文摘要

摘要： Contrary to the usual case when the quark mass spectrum is defined by that of the quark Yukawa couplings while the vacuum expectation value of the Higgs field remains universal, we suggest to consider the opposite situation. Each generation of quarks and leptons is associated with its own Higgs doublet, while the Yukawa couplings are the same. This situation naturally arises in the framework of finite supersymmetric Grand Unification scenario. Nondegeneracy of the quark mass spectrum is then due to asymmetric vacuum expectation values which spontaneously break the discrete flavour symmetry in the Higgs sector.
