非正则U(1)_Y大统一理论中的费米子质量和混合

Fermion Masses and Mixings in GUTs with Non-Canonical U(1)_Y

Ilia Gogoladze, Chin-Aik Lee, Tianjun Li, Qaisar Shafi

摘要:

本文讨论了从轨道大统一理论导出的模型中的费米子质量和混合,使得利用非正则U(1)_Y在没有低能超对称性的情况下实现规范耦合统一。规范U(1)X味对称性起着重要的作用,在反常抵消中,Green-Schwarz机制被调用。还讨论了含有质量接近M_{GUT}的矢量状粒子的模型。

英文摘要:

We discuss fermion masses and mixings in models derived from orbifold GUTs such that gauge coupling unification is achieved without low energy supersymmetry by utilizing a non-canonical U(1)_Y. A gauged U(1)_X flavor symmetry plays an essential role, and the Green-Schwarz mechanism is invoked in anomaly cancellations. Models containing vector-like particles with masses close to M_{GUT} are also discussed.
