走向规范统一的超对称隐强动力学

Towards gauge unified, supersymmetric hidden strong dynamics

Cheng-Wei Chiang, Sichun Sun, Fang Ye

摘要:

我们考虑一类模型与额外的复杂标量下收取的标准模型和隐藏的强耦合$SU(N)_H$规范部门,并讨论的情况下,新的标量被确定为信使字段,调解自发打破的超对称性从隐藏的部门可见的部门。新的标量嵌入到5-plets和10-plets的$SU(5)_V$规范组,可能统一的标准模型规范组。希格斯玻色子仍然是基本粒子。在这类模型的超对称化版本中,引入了类矢量费米子,其左手分量是新标量的超伴子。由于强相互作用的存在,新的低能标量在衰变前先强子化,从而避免了超对称方的直接搜索。这可以被看作是一个规范调解方案与标量信使场形成低能束缚态。我们还讨论了在隐藏的强动力学(至少TeV尺度)下形成的束缚态之塔中,其中之一是暗物质候选者的可能性,以及在不久的将来可能出现的模型的对撞机签名(例如,双光子,双玻色子或dijet)。

英文摘要:

We consider a class of models with extra complex scalars that are charged under both the Standard Model and a hidden strongly coupled $SU(N)_H$ gauge sector, and discuss the scenarios where the new scalars are identified as the messenger fields that mediate the spontaneously broken supersymmetries from the hidden sector to the visible sector. The new scalars are embedded into 5-plets and 10-plets of an $SU(5)_V$ gauge group that potentially unifies the Standard Model gauge groups. The Higgs bosons remain as elementary particles. In the supersymmetrized version of this class of models, vector-like fermions whose left-handed components are superperpartners of the new scalars are introduced. Due to the hidden strong force, the new low-energy scalars hadronize before decaying and thus evade the common direct searches of the supersymmetric squarks. This can be seen as a gauge mediation scenario with the scalar messenger fields forming low-energy bound states. We also discuss the possibility that among the tower of bound states formed under hidden strong dynamics (at least the TeV scale) one of them is the dark matter candidate, as well as the collider signatures (e.g. diphoton, diboson or dijet) of the models that may show up in the near future.
