寻找暗规范力的新固定靶实验

New Fixed-Target Experiments to Search for Dark Gauge Forces

James D. Bjorken, Rouven Essig, Philip Schuster, Natalia Toro

摘要:

固定靶实验非常适合通过与光子的动力学混合发现新的MeV-GeV质量U(1)规范玻色子。在本文中,我们确定了新的轻规范玻色子的生产和衰变特性,规定固定目标的搜索策略。我们总结了现有的限制,并提出了五个新的实验方法,我们预计可以覆盖大部分的自然参数空间,使用目前运行的GeV能量束和完善的检测方法。鉴于最近的地球和天体物理异常(PAMELA,FERMI,DAMA/LIBRA等),这些实验特别及时。与暗物质在新的规范力下带电的情况一致。

英文摘要:

Fixed-target experiments are ideally suited for discovering new MeV-GeV mass U(1) gauge bosons through their kinetic mixing with the photon. In this paper, we identify the production and decay properties of new light gauge bosons that dictate fixed-target search strategies. We summarize existing limits and suggest five new experimental approaches that we anticipate can cover most of the natural parameter space, using currently operating GeV-energy beams and well-established detection methods. Such experiments are particularly timely in light of recent terrestrial and astrophysical anomalies (PAMELA, FERMI, DAMA/LIBRA, etc.) consistent with dark matter charged under a new gauge force.
