摘要

我们说明了未来的电子-离子对撞机（EIC）如何用于发现质量在~ （10MeV−10GeV）范围内的暗玻色子，这些暗玻色子具有广泛的性质。我们只要求暗玻色子与电子具有不可忽略的弱耦合，并随O(1)分支分数衰变为不可见的最终态。我们的信号选择利用了优秀的电子束运动学测量和标记非相干散射的能力，正如EIC所设想的那样。这使得EIC成为一个强大的工具，用于发现潜在的黑暗部门力量，以及各种可能性。

Electron-ion collider as a discovery tool for invisible dark bosons

We illustrate how the future electron-ion collider (EIC) can be used to discover dark bosons with masses in the ∼(10MeV−10GeV) regime, having a wide range of properties. We only require that the dark bosons have a non-negligible weak coupling to electrons and decay with the O(1) branching fraction into invisible final states. Our signal selection takes advantage of the excellent electron beam kinematic measurements and the capability to tag incoherent scattering, as envisioned at the EIC. This makes the EIC a powerful tool for uncovering potential dark sector forces, for a variety of possibilities.
