We report preliminary results on a search for new phenomena in an event sample with monojets and large missing transverse momentum in the final state. The analysis uses 1.00 fb-1 of data collected in 2011 with the ATLAS detector. Good agreement is observed between the number of events in data and the Standard Model predictions. The results are translated into improved limits on a model with Large Extra Dimensions.

Unitarity and Monojet Bounds on Models for DAMA, CoGeNT, and CRESST-II
如果暗物质与夸克或胶子相互作用，这些相互作用的中介要么可以在大型强子对撞机上直接接触到，要么太重，以至于它的影响被编码在接触算符中。我们发现，在大型强子对撞机的接触算子描述的自洽性意味着边界上的调解人规模强于失踪的能量搜索。这转化为自旋无关的弹性散射截面，其水平小于10^-41 cm ^2，这直接影响到DAMA、CoGeNT和CRESST-II异常。然后，我们仔细探讨了单喷流搜索的潜力，在光介质限制，专注于任意耦合到夸克和暗物质的Z'模型。我们发现，Tevatron数据目前提供了最严格的界限暗物质和Z'质量低于100 GeV，这些搜索可以约束模型的DAMA，CoGeNT，和CRESST-II异常，只有当介质可以衰变到一对暗物质粒子。

事件的签名涉及大失踪的横向能量（MET）是典型的R-宇称守恒超对称性的搜索模式。CDF最近进行了两次使用MET和喷流的超对称性分析。MET和单喷流签名被用来确定过程独立的限制，为生产新的物理超越标准模型，然后应用到模型的自发破缺的超对称性，以确定限制的超对称性破缺参数和引力子质量。在超对称模型的框架内直接搜索标量顶夸克和标量底夸克，使用MET和两个重味喷流的签名。由于发现数据与标准模型预期一致，因此在质量平面$m (\tildeχ_{1}^{0}) - m (\tilde{t}_{1})$和$m (\tildeχ_{1}^{0}) - m (\tilde{b}_{1})$中确定限值。
