摘要:

精确规范耦合统一是低能或分裂超对称性的主要定量成功之一。保持这一成功对可能出现在对撞机可达能量处的物质和规范扇区提出了严格的限制。在这项工作中,我们列举了新的规范部门是兼容的统一,由水平规范组作用于矢量样物质下的标准模型收费。有趣的是,几乎所有这些理论在高能时都处于超对称共形窗口中,并且在超伴子解耦后很快被限制。对于一系列与适度调谐和最小分裂超对称性兼容的标量质量,约束动力学发生在多TeV尺度上,导致LHC可以获得多个自旋0和自旋1共振的光谱,具有不寻常的量子数和惊人的衰变模式。

英文摘要:

Precision gauge coupling unification is one of the primary quantitative successes of low energy or split supersymmetry. Preserving this success puts severe restrictions on possible matter and gauge sectors that might appear at collider-accessible energies. In this work we enumerate new gauge sectors which are compatible with unification, consisting of horizontal gauge groups acting on vector-like matter charged under the Standard Model. Interestingly, almost all of these theories are in the supersymmetric conformal window at high energies and confine quickly after the superpartners are decoupled. For a range of scalar masses compatible with both moderately tuned and minimally split supersymmetry, the confining dynamics happen at the multi-TeV scale, leading to a spectrum of multiple spin-0 and spin-1 resonances accessible to the LHC, with unusual quantum numbers and striking decay patterns.
