摘要:

我们考虑最小的暗物质的情况下,具有动量依赖耦合的黑暗部门的标准模型。我们从现有的LHC搜索单喷通道的约束,估计未来的LHC灵敏度为300 FB $^{-1}$的积分亮度,并与模型表现出传统的动量无关的相互作用与黑暗的部门进行比较。除了受到(复合)伪戈德斯通暗物质场景的启发外,动量相关耦合也很有趣,因为它们削弱了直接检测的限制。对于一个特定的暗物质质量,大型强子对撞机原来是敏感的动量依赖的情况下,由于更硬的射流横向动量分布的信号截面较小。

英文摘要:

We consider minimal dark matter scenarios featuring momentum-dependent couplings of the dark sector to the Standard Model. We derive constraints from existing LHC searches in the monojet channel, estimate the future LHC sensitivity for an integrated luminosity of 300 fb$^{-1}$, and compare with models exhibiting conventional momentum-independent interactions with the dark sector. In addition to being well motivated by (composite) pseudo-Goldstone dark matter scenarios, momentum-dependent couplings are interesting as they weaken direct detection constraints. For a specific dark matter mass, the LHC turns out to be sensitive to smaller signal cross-sections in the momentum-dependent case, by virtue of the harder jet transverse-momentum distribution.
