论文摘要
我们探索当前的对撞机搜索的约束,位于QCD样黑暗扇区上。多喷射,多喷射加上缺失的能量和新兴喷气机搜索的组合用于首次对整个黑暗中膜寿命的介体质量的约束。黑暗扇区从深色夸克和通过中介者之间的Quark之间的耦合继承了一种风味结构。考虑到这一点时,味道不同的黑亲生在其一生中就可以区分。我们表明,在这些情况下,上述搜索仍然很敏感,并且在调味的情况下也获得了调解器质量的限制。然后,我们将对撞机搜索的约束与在风味和未散发的场景中的暗物质候选者身上的直接检测范围进行了对比。使用简单的处方,可以在暗物质和中介质量平面中显示所有约束。直接检测的约束往往比对撞机的约束更强,除非抑制了与第一代夸克的耦合,否则对撞机搜索将对参数空间的最严格限制限制。
We explore the constraints current collider searches place on a QCD-like dark sector. A combination of multi-jet, multi-jet plus missing energy and emerging jets searches is used to derive constraints on the mediator mass across the full range of the dark meson lifetimes for the first time. The dark sector inherits a flavour structure from the coupling between the dark quarks and the SM quarks through the mediator. When this is taken into account, the differently flavoured dark pions become distinguishable through their lifetime. We show that also in these cases the above mentioned searches remain sensitive, and we obtain limits on the mediator mass also for the flavoured scenario. We then contrast the constraints from collider searches with direct detection bounds on the dark matter candidate itself in both the flavoured and unflavoured scenario. Using a simple prescription it becomes possible to display all constraints in the dark matter and mediator mass plane. Constraints from direct detection tend to be stronger than the collider constraints, unless the coupling to the first generation quarks is suppressed, in which case the collider searches place the most stringent limits on the parameter space.
