标题： Pulsar kicks in ultralight dark matter background induced by neutrino oscillation

摘要： 中微子与超轻标量和矢量暗物质背景的相互作用会诱导中微子色散关系的修正。 本文在超新星核心中不对称发射中微子（进而脉冲星反冲）的框架下回顾了这种修正的影响。 我们考虑了中微子振荡，特别是关注活性-无菌转换。 超轻暗物质引起的中微子色散关系包含一个形式为 $\delta {\bf \Omega}\cdot \hat{{\bf{p}}}$ 的项，其中 $\delta {\bf \Omega}$ 与超轻暗物质场有关，而 $\hat{{\bf p}}$ 是沿中微子动量方向的单位向量。 ${\bf p}$ 与 $\delta {\bf \Omega}$ 的相对取向影响观测到的脉冲星速度生成机制。 我们在超轻暗物质背景下得到了活性-无菌中微子振荡的共振条件，并计算了共振面上的恒星参数，使得超轻标量和矢量暗物质背景都能解释观测到的脉冲星反冲。 在超轻暗物质背景下，中微子的不对称发射会产生引力记忆信号，该信号可以通过未来的引力波探测器（如adLIGO、adVIRGO、DECIGO、BBO和ET）来探测。 我们还建立了超轻暗物质参数与洛伦兹和CPT不变性破坏参数之间的关系。 显示英文摘要

摘要： The interaction of neutrinos with ultralight scalar and vector dark matter backgrounds induce a modification of the neutrino dispersion relation. The effects of this modification are reviewed in the framework of asymmetric emission of neutrinos from the supernova core, and, in turn, of pulsar kicks. We consider the neutrino oscillations, focusing in particular to active-sterile conversion. The ultralight dark matter induced neutrino dispersion relation contains a term of the form $\delta {\bf \Omega}\cdot \hat{{\bf{p}}}$, where $\delta {\bf \Omega}$ is related to the ultralight dark matter field and $\hat{{\bf p}}$ is the unit vector along the direction of neutrino momentum. The relative orientation of ${\bf p}$ with respect to $\delta {\bf \Omega}$ affects the mechanism for the generation of the observed pulsar velocities. We obtain the resonance condition for the active-sterile neutrino oscillation in ultralight dark matter background and calculate the star parameters in the resonance surface so that both ultralight scalar and vector dark matter backgrounds can explain the observed pulsar kicks. The asymmetric emission of neutrinos in presence of ultralight dark matter background results gravitational memory signal which can be probed from the future gravitational wave detectors such as adLIGO (advanced LIGO), adVIRGO (advanced VIRGO), DECIGO (DECi-hertz Interferometer Gravitational wave Observatory), BBO (Big Bang Observer), and ET (Einstein Telescope). We also establish a relation between the ultralight dark matter parameters and the Lorentz and CPT invariance violation parameters.
