论文摘要
基于加速器的暗物质搜索旨在提高高灵敏度，需要具有高光度的实验设置。该研究领域通常称为强度边界物理学。暗物质和普通物质之间最好的动机门户之一是深色光子，可以将其视为不变质量的衰减产物中的共鸣。众所周知，电子峰值碰撞是此类研究的最干净相互作用。在本文中，我们提出了一个对撞机的方案，该方案的发光度比传统的对称对撞机中获得的数量级高几个数量级，并且比使用正电子梁和固定目标接近的可能性高几倍可访问质量。关键概念基于不对称能量：高能循环正电子束和低能的高强度电子束，以及束相互作用区域的优化。我们在这里提出了10 MEV电子和4个GEV正电子梁的碰撞区域的配置。
Accelerator-based searches for dark matter are aiming for high sensitivity and need an experimental setup with high luminosity. This field of research is often called intensity frontier physics. One of the best motivated portals of interaction between dark matter and ordinary matter is a dark photon which could be observed as a resonance in the invariant mass of the decay products. Electron-positron collisions are known to be the cleanest interaction for such a study. In this paper we propose a scheme for a collider which allows for a luminosity of a few orders of magnitude higher than could be obtained in a conventional symmetric collider and with a few times higher accessible mass than is possible using a positron beam and a fixed target approach. The key concept is based on asymmetric energies: a high-energy circulating positron beam and a low-energy high-intensity electron beam, and optimization of the beam interaction region. We present here a configuration of a collision region of 10 MeV electron and 4 GeV positron beams.
