论文摘要
我们研究了与随机重力波（GWS）相互作用的固定大规模中微子的演化和振荡。这些GWS的能量谱是高斯，振幅的相关因子是任意的。在这种情况下，我们得出了风味中微子的密度矩阵的方程。在两个口味近似中，可以通过分析求解该方程。我们在三种中微子风味的一般情况下找到了密度矩阵的数值解。我们认为将二进制黑洞合并为与逼真的光谱的随机GW的来源。分析了正常和倒数的质量顺序。我们讨论主要由超级黑洞发出的随机GW中中微子通量的放松。在这种情况下，我们获得了能量的范围和放松过程最有效的传播长度。我们讨论了我们的结果在观察天体物理中微子通量中的应用。
We study the evolution and oscillations of fixed massive neutrinos interacting with stochastic gravitational waves (GWs). The energy spectrum of these GWs is Gaussian, with the correlator of the amplitudes being arbitrary. We derive the equation for the density matrix for flavor neutrinos in this case. In the two flavors approximation, this equation can be solved analytically. We find the numerical solution for the density matrix in the general case of three neutrino flavors. We consider merging binary black holes as sources of stochastic GWs with realistic spectra. Both normal and inverted mass orderings are analyzed. We discuss the relaxation of the neutrino fluxes in stochastic GWs emitted mainly by supermassive black holes. In this situation, we obtain the range of energies and the propagation lengths for which the relaxation process is the most efficient. We discuss the application of our results for the observation of fluxes of astrophysical neutrinos.
