非对易几何中的SU(5)轨道二重GUT

SU(5) orbifold GUT in noncommutative geometry

Masaki J. S. Yang

摘要:

在本文中,我们将轨道大统一理论机制应用于非对易几何中的SU(5)模型,包括费子扇区。通过对玻色子和费米子的“组成场”进行适当的宇称赋值,费米子和重玻色子$X_μ, Y_μ$以及$ H^{c}$之间的耦合被宇称对称性所禁止。结果表明,导出的费米子拉氏量与标准模型的拉氏量完全一致,质子衰变在树能级上是被禁止的。如果量子涨落遵守宇称对称性,则这一过程将被自然抑制甚至完全禁止。

英文摘要:

In this paper, we appliy the orbifold GUT mechanism to the SU(5) model in noncommutative geometry, including the fermonic sector. Imposing proper parity assignments for "constituent fields" of bosons and fermions, the couplings between fermions and the heavy bosons $X_μ, Y_μ$, and $ H^{c}$ are prohibited by the parity symmetry. As a result, the derived fermionic Lagrangian is just that of the standard model, and proton decay is forbidden at tree level. If quantum fluctuation respects the parity symmetry, the process will be naturally suppressed or even forbidden completely.
