可能的第五种力与直接探测暗物质之间的联系

Connection between a possible fifth force and the direct detection of Dark Matter

Jo Bovy, Glennys R. Farrar

摘要:

如果在暗区存在第五种力,并且暗区粒子与普通物质的相互作用是非引力的,那么量子修正通常会导致可见区的第五种力。我们展示了如何强大的实验限制第五部队在可见部门约束的直接检测截面,和第五部队在黑暗的部门的强度。如果后者与重力相当,则与自旋无关的直接探测截面通常必须<~ 10^{-55} cm ^2。落向暗物质的普通物质的反常加速度也受到限制:η_{OM-DM} <~ 10^{-8}。

英文摘要:

If there is a fifth force in the dark sector and dark sector particles interact non-gravitationally with ordinary matter, quantum corrections generically lead to a fifth force in the visible sector. We show how the strong experimental limits on fifth forces in the visible sector constrain the direct detection cross section, and the strength of the fifth force in the dark sector. If the latter is comparable to gravity, the spin-independent direct detection cross section must typically be <~ 10^{-55} cm^2. The anomalous acceleration of ordinary matter falling towards dark matter is also constrained: η_{OM-DM} <~ 10^{-8}.
