长波引力波的散射

Scattering of Long-Wavelength Gravitational Waves

Sam R. Dolan

摘要:

研究了真空中大质量致密体对低频引力波的散射。我们应用分波方法计算振幅的螺旋度守恒和螺旋度反转的贡献的横截面,精确到一阶$Mω$。与以前的说法相反,我们发现,分波截面同意通过微扰理论方法推导出的截面。

英文摘要:

We consider the scattering of a low-frequency gravitational wave by a massive compact body in vacuum. We apply partial-wave methods to compute amplitudes for the helicity-conserving and helicity-reversing contributions to the cross section, accurate to first order in $Mω$. Contrary to previous claims, we find that the partial-wave cross section agrees with the cross section derived via perturbation-theory methods.
