论文摘要
本文研究了标量张量理论中产生的标量第五力的特性，并在重力空间任务（如显微镜实验）的背景下具有变色龙筛选机制。在这样的实验中，实验嵌套圆柱体内的变色龙场的繁殖会导致圆柱体并非完全同轴时。我们提出了一种半分析方法来计算场分布和诱导的第五力，并将其与完整的数值模拟进行比较，在圆柱对称性破裂的设置中。讨论了第五力与模型参数和实验几何形状的缩放。我们表明，第五力是令人反感的，因此增加了一个不稳定的刚度，应包括在探测器上作用的力预算中。这为在筛选模型中限制标量第五力的新方法开辟了道路。
This article investigates the properties of a scalar fifth force that arises in a scalar tensor-theory with a chameleon screening mechanism in the context of gravity space missions like the MICROSCOPE experiment. In such an experiment, the propagation of the chameleon field inside the nested cylinders of the experiment causes a fifth force when the cylinders are not perfectly co-axial. We propose a semi-analytic method to compute the field distribution and the induced fifth force and compare it to a full numerical simulation, in settings where the cylindrical symmetry is broken. The scaling of the fifth force with both the parameters of the model and the geometry of the experiment is discussed. We show that the fifth force is repulsive, hence adds a destabilizing stiffness that should be included in the force budget acting on the detector. This opens the way to a new method to constrain a scalar fifth force in screened models.
