论文摘要
爱因斯坦的总体相对论是最成功的重力理论，是现代物理学的基石之一。但是，高能量区域的重力测试受到限制。新兴的引力波天文学为探测强力和动态场，尤其是高能量状态的重力的基本特性开辟了一条途径。在这项工作中，我们通过重力波测试重力的平均保存。如果均衡对称性被打破，重力波的左手和右手模式将遵循不同的运动方程式，被称为双重反发。我们通过将最新的波形与均等违规与紧凑型二元合并数据进行比较，通过将最新的波形与Ligo和Pirgo Collaboration发布的紧凑型二元合并数据进行比较，进行了完整的贝叶斯推断。我们没有发现任何违反一般相对性的行为，因此通过引力波的速度双折射，将平等能量量表的下限限制为$ 0.09 $ GEV。这提供了最新的重力平价对称性的最严格的实验测试。我们还发现，如果仍然没有违规行为，则第三代重力波检测器可以增强其与$ \ MATHCAL {O}（10^2）$ GEV绑定，与当前粒子物理学中的LHC能量量表相当，这表明在高能量区域中测试Graviolet gravity的新时代，这表明在高能量区域的新时代都可以迎来。
Einstein's general relativity, as the most successful theory of gravity, is one of the cornerstones of modern physics. However, the experimental tests for gravity in the high energy region are limited. The emerging gravitational-wave astronomy has opened an avenue for probing the fundamental properties of gravity in strong and dynamical field, and in particular, high energy regime. In this work, we test the parity conservation of gravity with gravitational waves. If the parity symmetry is broken, the left- and right-handed modes of gravitational waves would follow different equations of motion, dubbed as birefringence. We perform full Bayesian inference by comparing the state-of-the-art waveform with parity violation with the compact binary coalescence data released by LIGO and Virgo collaboration. We do not find any violations of general relativity, thus constrain the lower bound of the parity-violating energy scale to be $0.09$ GeV through the velocity birefringence of gravitational waves. This provides the most stringent experimental test of gravitational parity symmetry up to date. We also find third generation gravitational-wave detectors can enhance this bound to $\mathcal{O}(10^2)$ GeV if there is still no violation, comparable to the current LHC energy scale in particle physics, which indicates gravitational-wave astronomy can usher in a new era of testing the ultraviolet behavior of gravity in the high energy region.
