论文摘要
我们讨论了在两个黑洞合并中产生的重力波信号的弦乐$ {α'} $校正。我们与标准顶点操作员或相干状态描述的异质字符串中的两个BPS紧凑型物体合并对合并进行了建模。尽管预期的立方抑制在$ {α'} $ W.R.T.中总体相对性结果，在树级上，字符串校正似乎在Aligo/处女座和未来干涉仪的灵敏度区域内的重力波信号上留下了足迹或记忆。包括扩大和破坏字符串共振的循环效应表明，一种丢失的弦记忆效应，可以通过对降落阶段的准正常模式进行分析来恢复。
We discuss stringy ${α'}$ corrections to the gravitational wave signal generated in the merging of two black holes. We model the merging with two BPS compact massive objects in the heterotic string, described by standard vertex operators or coherent states. Despite the expected cubic suppression in ${α'}$ w.r.t. the General Relativity result, at tree level the string corrections seem to leave a footprint or a memory on the gravitational wave signals within the sensitivity region of aLIGO/VIRGO and future interferometers. Including loop effects that broaden and destabilise the string resonances suggests a sort of lost stringy memory effect that can be regained through the analysis of the quasi normal modes in the ring-down phase.
