没有大统一的夸克和轻子的关系

Relating quarks and leptons without grand-unification

S. Morisi, E. Peinado, Yusuke Shimizu, J. W. F. Valle

摘要:

结合超对称性,味对称性可以将夸克与轻子联系起来,即使在没有大统一群的情况下。我们提出了一个SU(3)xSU(2)xU(1)模型,其中超对称性和假设的A4味对称性都是软破缺的,很好地再现了观测到的费米子质量等级,并预言:(i)下型夸克和带电轻子质量之间的关系,(ii)夸克扇区的Cabibbo角和表征中微子振荡中CP破坏的反应器角之间的相关性.

英文摘要:

In combination with supersymmetry, flavor symmetry may relate quarks with leptons, even in the absence of a grand-unification group. We propose an SU(3)xSU(2)xU(1) model where both supersymmetry and the assumed A4 flavor symmetries are softly broken, reproducing well the observed fermion mass hierarchies and predicting: (i) a relation between down-type quarks and charged lepton masses, and (ii) a correlation between the Cabibbo angle in the quark sector, and the reactor angle characterizing CP violation in neutrino oscillations.
