用引力波束缚引力子质量:引力波模板中高次谐波的影响

Bounding the mass of the graviton with gravitational waves: Effect of higher harmonics in gravitational waveform templates

K G Arun, Clifford M Will

摘要:

利用激光干涉仪探测器对来自螺旋压缩双星系统的引力波的观测,可以用来寻找波的传播速度对波长的依赖关系,从而确定一个假定引力子的质量或康普顿波长。我们研究的效果,包括高次谐波,以及他们的后牛顿振幅校正,在模板重力波形的参数估计过程中使用匹配滤波。我们认为,可以实现使用先进的LIGO,拟议的第三代仪器称为爱因斯坦望远镜,和拟议的空间干涉仪LISA的界限。我们发现,在所有的情况下,引力子康普顿波长的界限改善了几乎一个数量级的更高的质量时,包括振幅校正。

英文摘要:

Observations by laser interferometric detectors of gravitational waves from inspiraling compact binary systems can be used to search for a dependence of the waves' propagation speed on wavelength, and thereby to bound the mass or Compton wavelength of a putative graviton. We study the effect of including higher harmonics, as well as their post-Newtonian amplitude corrections, in the template gravitational waveforms employed in the process of parameter estimation using matched filtering. We consider the bounds that could be achieved using advanced LIGO, a proposed third generation instrument called Einstein Telescope, and the proposed space interferometer LISA. We find that in all cases, the bounds on the graviton Compton wavelength are improved by almost an order of magnitude for higher masses when amplitude corrections are included.
