拥有磁性人格的胖希格斯

A Fat Higgs with a Magnetic Personality

Nathaniel Craig, Daniel Stolarski, Jesse Thaler

摘要:

本文介绍了一种新的基于约束超对称QCD的复合Higgs理论。超对称对偶性在这个结构中扮演了关键的角色,一个“胖”的希格斯玻色子玻色子作为一个在对偶磁规范群下带电的对偶磁自由度出现。由于红外线中自发的色味锁定,电弱规范对称性与对偶磁规范群对齐,允许基本物质场和复合希格斯粒子之间的大汤川耦合。与此同时,该理论表现出亚稳态超对称性破缺,导致通过复合信使的低尺度规范调解。希格斯玻色子比最小超对称理论中的更重,这是由于非解耦的D项和大的F项四次耦合。这个理论预测了准稳定的TeV尺度的赝模,其中一些在标准模型颜色下带电,可能在LHC中产生长寿命的R-强子。

英文摘要:

We introduce a novel composite Higgs theory based on confining supersymmetric QCD. Supersymmetric duality plays a key role in this construction, with a "fat" Higgs boson emerging as a dual magnetic degree of freedom charged under the dual magnetic gauge group. Due to spontaneous color-flavor locking in the infrared, the electroweak gauge symmetry is aligned with the dual magnetic gauge group, allowing large Yukawa couplings between elementary matter fields and the composite Higgs. At the same time, this theory exhibits metastable supersymmetry breaking, leading to low-scale gauge mediation via composite messengers. The Higgs boson is heavier than in minimal supersymmetric theories, due to non-decoupling D-terms and a large F-term quartic coupling. This theory predicts quasi-stable TeV-scale pseudo-modulini, some of which are charged under standard model color, possibly giving rise to long-lived R-hadrons at the LHC.
