大型强子对撞机上的超对称单喷流

Supersymmetric Monojets at the Large Hadron Collider

Benjamin C. Allanach, Sebastian Grab, Howard E. Haber

摘要:

在大型强子对撞机上,超对称的单喷流可以通过qg -> squark neutralino_1 -> q neutralino_1 neutralino_1的过程产生,导致喷流因失去横向动量而反冲。我们讨论了超对称单喷流信号的可行性和实用性。特别是,我们研究了可能的精度,其中一个可以确定的neutralino_1-quark-quark耦合通过速率的单喷事件。这样的耦合包含了neutralino_1的组成信息,并有助于结合暗物质直接探测截面和neutralino_1的暗物质遗迹密度。它还提供了一个检查规范耦合和规范夸克夸克耦合之间的超对称关系。

英文摘要:

Supersymmetric monojets may be produced at the Large Hadron Collider by the process qg -> squark neutralino_1 -> q neutralino_1 neutralino_1, leading to a jet recoiling against missing transverse momentum. We discuss the feasibility and utility of the supersymmetric monojet signal. In particular, we examine the possible precision with which one can ascertain the neutralino_1-squark-quark coupling via the rate for monojet events. Such a coupling contains information on the composition of the neutralino_1 and helps bound dark matter direct detection cross-sections and the dark matter relic density of the neutralino_1. It also provides a check of the supersymmetric relation between gauge couplings and gaugino-quark-squark couplings.
