轻子和夸克质量的起源

On the Origin of Lepton and Quark Masses

Jiri Hosek, J. Adam,

摘要:

测量标准模型的手征费米子场的味(族、代、水平)指数,对于由三个无菌右手中微子场扩展的反常自由,导致渐近自由的、{ \it bona fide}非限制的$SU(3)_f$量子味动力学。相应的费米子自能Schwinger-Dyson(SD)方程的近似非微扰强耦合解导致完全味对称破缺:(1)三个巨大的Majorana质量的无菌右手中微子。(2)三个指数轻狄拉克质量共同所有费米子种类在一个家庭。带电轻子和夸克的质量与狄拉克中微子质量的进一步区别在于弱超荷对SD方程的普适$SU(3)_f$核的贡献,不含未知参数。因此,$SU(3)_f$动力学本身给出了跷跷板形式的中微子质谱。

英文摘要:

Gauging the flavor (family, generation, horizontal) index of the chiral fermion fields of the Standard model, for anomaly freedom extended by three sterile right-handed neutrino fields, results in asymptotically free, {\it bona fide} nonconfining $SU(3)_f$ quantum flavor dynamics. Approximate nonperturbative strong-coupling solutions of the corresponding Schwinger-Dyson (SD) equation for fermion self-energies give rise to the complete flavor symmetry breaking by : (1) Three huge Majorana masses of sterile right-handed neutrinos. (2) Three exponentially light Dirac masses common to all fermion sorts in a family. Masses of charged leptons and quarks are further distinguished from Dirac neutrino masses by the weak hypercharge contributions to the universal $SU(3)_f$ kernel of the SD equation, free of unknown parameters. The $SU(3)_f$ dynamics itself thus gives the neutrino mass spectrum in the seesaw form.
