弱相互作用大质量粒子(WIMP)范式是粒子暗物质(DM)最引人注目的场景之一。我们表明,在本文中,高能μ子对撞机可以作出决定性的声明WIMP DM,这应该作为其主要的物理驱动程序的情况之一。我们证明了这一点,采用DM作为最轻的成员的电弱(EW)多重态,这是一个简单的,但最具挑战性的WIMP方案之一,其最小的对撞机签名和高热目标的质量尺度为1 - 23 TeV。我们进行了第一次研究的范围内的高能量μ子对撞机,专注于简单,包容性,和保守的信号与大的丢失质量,通过单光子,矢量玻色子融合双μ子和一个新的单μ子通道。使用这些包容性的信号,它是可能的,以涵盖与10 TeV μ子对撞机的双重和三重态的热目标。更高的能量,14 TeV-75 TeV,将确保更高EW多重态的热目标以上的区域。我们还估计了搜索消失的轨道的范围,表明潜在的显着增强的灵敏度。
The weakly interacting massive particle (WIMP) paradigm is one of the most compelling scenarios for particle dark matter (DM). We show in this paper that a high energy muon collider can make decisive statements about the WIMP DM, and this should serve as one of its main physics driver cases. We demonstrate this by employing the DM as the lightest member of an electroweak (EW) multiplet, which is a simple, yet one of the most challenging WIMP scenarios given its minimal collider signature and high thermal target mass scale of 1–23 TeV. We perform a first study of the reach of high energy muon colliders, focusing on the simple, inclusive, and conservative signals with large missing mass, through the mono-photon, vector boson fusion di-muon and a novel mono-muon channel. Using these inclusive signals, it is possible to cover the thermal targets of doublet and triplet with a 10 TeV muon collider. Higher energies, 14 TeV–75 TeV, would ensure areach above the thermal targets for the higher EW multiplets. We also estimate the reach of a search for disappearing tracks, demonstrating the potential significant enhancement of the sensitivity.
