$SU(9)$轨道族统一的预言

Predictions of $SU(9)$ orbifold family unification

Yuhei Goto, Yoshiharu Kawamura

摘要:

研究了含轨道$T^2/Z_2$的六维时空中具有$SU(9)$规范群的轨道族统一模型的预言,得到了超对称扩展模型中sfermion质量之间的关系.该模型的一个突出特点是在$[9, 3]$表象中,一对Weyl费米子中只存在三个标准模型费米子族,它们是四维零模,没有伴随任何镜像粒子.

英文摘要:

We study predictions of orbifold family unification models with $SU(9)$ gauge group on a six-dimensional space-time including the orbifold $T^2/Z_2$, and obtain relations among sfermion masses in the supersymmetric extension of models. The models have an excellent feature that just three families of the standard model fermions exist in a pair of Weyl fermions in the $[9, 3]$ representation as four-dimensional zero modes, without accompanying any mirror particles.
