使用SO实现家族统一(10)

Family Unification with SO(10)

K. S. Babu, S. M. Barr, Ilia Gogoladze

摘要:

研究了基于群SO(10)^3 \times S_3的统一.每个族都有自己的SO(10)群,S_3置换了三个族和SO(10)因子。这是已知费米子的最大局部对称性。在这个意义上,所有已知的费米子都在一个不可约的多重对称中,从而实现了族统一。对称性通过使所有的方子和slepton在对称性极限内退化来抑制超对称味道改变效应。双三重态分裂可以简单地产生,夸克和轻子质量的非平凡结构从规范对称性中出现,包括“双不平衡”形式。

英文摘要:

Unification based on the group SO(10)^3 \times S_3 is studied. Each family has its own SO(10) group, and the S_3 permutes the three families and SO(10) factors. This is the maximal local symmetry for the known fermions. Family unification is achieved in the sense that all known fermions are in a single irreducible multiplet of the symmetry. The symmetry suppresses SUSY flavor changing effects by making all squarks and sleptons degenerate in the symmetry limit. Doublet-triplet splitting can arise simply, and non-trivial structure of the quark and lepton masses emerges from the gauge symmetry, including the "doubly lopsided" form.
