古怪的小希格斯模型

A Quirky Little Higgs Model

Haiying Cai, Hsin-Chia Cheng, John Terning

摘要:

我们考虑一个额外的维模型,其中的二次发散的顶圈贡献的希格斯质量被一个无色的重的“顶夸克”在不同的SU(3)规范群下收费取消。这种抵消是由体规范对称性所强制的。因此,我们有一个不寻常的小希格斯模型,它有一些古怪的签名。这个模型中的最高伙伴可以在大型强子对撞机上找到,因为宏观弦连接了夸克和反夸克。该模型可以进行辐射电弱对称性破缺,并与精密电弱测量是一致的。

英文摘要:

We consider an extra dimensional model where the quadratically divergent top loop contribution to the Higgs mass is cancelled by an uncolored heavy "top quirk" charged under a different SU(3) gauge group. The cancellation is enforced by bulk gauge symmetries. Thus we have an unusual type of little Higgs model which has some quirky signatures. The top partner in this model could be identified at the Large Hadron Collider due to macroscopic strings that connect quirk and anti-quirks. The model can undergo radiative electroweak symmetry breaking and is consistent with precision electroweak measurements.
