单极凝聚的电弱对称破缺

Electroweak Symmetry Breaking From Monopole Condensation

Csaba Csaki, Yuri Shirman, John Terning

摘要:

我们研究模型,无质量手征费米子与“电”和“磁”超荷可以形成凝聚。当某些费米子同时也是电弱二重态时,这样的凝聚体就能以正确的方式打破电弱规范对称性,使之成为电磁场。由于普通超荷在TeV尺度下是弱耦合的,磁超荷是强耦合的,可以潜在地驱动凝聚。这种模型类似于特色,但超荷扮演了特色规范群的角色,所以标准模型规范群会自我分裂。一个重的顶部质量可以通过鲁巴科夫-卡兰效应产生,从而可以将风味物理学的尺度与电弱尺度解耦。

英文摘要:

We examine models where massless chiral fermions with both "electric" and "magnetic" hypercharges could form condensates. When some of the fermions are also electroweak doublets such condensates can break the electroweak gauge symmetry down to electromagnetism in the correct way. Since ordinary hypercharge is weakly coupled at the TeV scale, magnetic hypercharge is strongly coupled and can potentially drive the condensation. Such models are similar to technicolor, but with hypercharge playing the role of the technicolor gauge group, so the standard model gauge group breaks itself. A heavy top mass can be generated via the Rubakov-Callan effect and could thus decouple the scale of flavor physics from the electroweak scale.
