Scalar Domain Walls in Laboratory Experiments

我们想设计一个实验来探测由一种新的光标量场所介导的第五种力，这种场可以起到暗物质或暗能量的作用。在参数空间中存在一个以前未探索过的区域，在该区域中，真空室可以抵消任何外部影响，从而使第五种力的影响可被检测到。一个好的真空将导致一个非常低的密度环境，在这个环境中，对称子可以与引力强度耦合，物质粒子上的标量场是潜在的可观测的。对称子理论包括一个特有的相变；从宇宙学上讲，这个相变发生在宇宙膨胀和冷却的时候。随着相变的发生，可能会形成拓扑缺陷(“域壁”)。人们希望通过设计和制造一种根据拓扑结构量身定做的吸尘器，通过将它们绑定到腔体内部来确保这些磁化壁长寿命。然后我们可以进行粒子实验，在这个实验中，物质粒子入射到磁区壁上。当物质粒子接近磁区壁时，它将经历标量场所传递的第五种力，并将被偏转，甚至可能被反射出磁区壁。这种偏转或反射是第五种力的标志，可能会限制黑暗部分以前不受限制的部分。

We would like to design an experiment to detect the fifth force mediated by a new light scalar field that can play the role of dark matter or dark energy. There exists a previously unexplored region of parameter space in which a vacuum chamber can nullify any outside effects and thus make the effects of the fifth force detectable. A good vacuum will result in a very low density environment in which the symmetron can couple with gravitational strength, and the scalar field on a matter particle are potentially observable. Symmetron theories include a characteristic phase transition; cosmologically speaking, this transition occurs as the universe expands and cools. As the phase transition occurs, topological defects can form ("domain walls"). It is hoped that by designing and manufacturing a topologically-tailored vacuum cleaner, we can ensure that theses domain walls are long-lived by binding them to the interior of the chamber. We can then perform a particle experiment in which a matter particle is incident on a domain wall. As the matter particle approaches the domain wall, it will experience that fifth force mediated by the scalar field and will be deflected or possibly even reflected off the domain wall. This deflection or reflection is a signature of the fifth force and could constrain some previously unconstrained parts of the dark sector.
