极紧凑源周围的第五种力屏蔽

Fifth-Force Screening around Extremely Compact Sources

Clare Burrage, Benjamin Elder, Peter Millington, Daniela Saadeh, Ben Thrussell

摘要:

许多非线性标量场理论拥有一种屏蔽机制,可以在稠密环境中抑制任何相关的第五种力。因此,这些理论可以逃避当地对新势力的实验检验。由于标量势的非线性或与物质的耦合而发生的变色龙般的屏蔽,在扩展物体周围是很好理解的。然而,这些理论的许多实验测试涉及空间范围远小于标量场的康普顿波长的物体,因此可以被认为是点状的。在这项工作中,我们确定如何筛选的第五种力量的限制,源对象变得非常紧凑。

英文摘要:

Many non-linear scalar field theories possess a screening mechanism that can suppress any associated fifth force in dense environments. As a result, these theories can evade local experimental tests of new forces. Chameleon-like screening, which occurs because of non-linearities in the scalar potential or the coupling to matter, is well understood around extended objects. However, many experimental tests of these theories involve objects with spatial extent much smaller than the scalar field's Compton wavelength, and which could therefore be considered point-like. In this work, we determine how the fifth forces are screened in the limit that the source objects become extremely compact.
