弯曲空间中体费米子和膜费米子的最吸引道研究

Most-attractive-channel study for bulk and brane fermions in warped space

Nobuhiro Uekusa

摘要:

将标准模型规范对称性的自破缺思想应用于翘曲空间中的规范理论。我们系统地研究了体费米子和膜费米子的规范耦合。在不凝聚四维无质量胶子和不形成色三重标量束缚态的条件下,发现了体费米子质量的约束。对于左手和右手分量为零模的体费米子,质量参数至少分别为$c\simg 1/2$和$c\siml -1/2$。那么可能的真空期望值只产生于触发电弱对称破缺的弱二重标量束缚态。

英文摘要:

The idea of the self-breaking of the standard model gauge symmetry is applied to a gauge theory in a warped space. We systematically examine the gauge couplings of bulk and brane fermions. The constraint on the masses of bulk fermions is found under the conditions that the ordinary four-dimensional massless gluon is not condensed and that color-triplet scalar bound states are not formed. For bulk fermions with zero modes for the left- and right-handed components, the mass parameters are required to be at least $c\simg 1/2$ and $c\siml -1/2$, respectively. Then possible vacuum expectation values arise only from weak-doublet scalar bound states which trigger electroweak symmetry breaking.
