论文摘要
从二进制黑洞来源发现引力波的检测使在黑洞上寻找电荷和“黑暗”电荷的可能性，后者是暗物质的候选人。这需要关于指控对二进制黑洞灵感的影响的理论预测，以便对指控施加限制。这些电荷对二进制黑洞灵感的影响可以使用爱因斯坦 - 马克斯韦尔理论来描述。它们以前已被派往纽顿后第一个（1pn）的订单，最近使用的结果将其在黑洞上的电荷与质量比下限制。在这里，我们将有效的现场理论方法与基于颞kaluza-klein分解的指标参数化，并具有非偏好的引力场，以达到拉格朗日的二进制运动，该二进制运动在指控的影响下最高2pn顺序。
The detection of gravitational waves from binary black holes sources has opened the possibility to search for electric charges and "dark" charges on black holes, the latter being candidates for dark matter. This requires theoretical predictions about the effect of charges on the inspiral of binary black holes in order to place constraint on charges. The effects of these charges on the inspiral of binary black holes can be described using Einstein-Maxwell theory. They have previously been derived up to first post-Newtonian (1PN) order, and the results were recently used to place bounds on the charge-to-mass ratio on black holes. Here we use the effective field theory approach with a metric parameterization based on a temporal Kaluza-Klein decomposition with non-relativistic gravitational fields to arrive at the Lagrangian for binary motion under the influence of charges up to 2PN order.
