论文摘要
我们提出了一个场景，其中MEV-TEV球场中光中微子质量和重力暗物质（DM）的高度SEESAW起源起源于原始黑洞（PBH）蒸发，可以通过多个倾斜或光谱或频谱断裂的未来观察到未来的随机重力波（GW）背景来探测。 Abelian仪表对称性的高度破裂确保了Seesaw量表的动态起源，同时还导致了负责产生随机GW背景的宇宙字符串的形成。在该球场中正确的DM遗物的要求需要将稀释液包含在PBH通常导致DM生产过多时。这导致第二次早期物质在PBH蒸发后由于长期寿命稀释剂而占主导地位。这两个早期的物质主导了与DM遗物相关的时期，导致宇宙弦形成的原本尺度不变的GW光谱中的多个光谱断裂。我们发现DM质量与GW频谱的转折点频率之间的有趣相关性，这些频率在丽莎，BBO，ET，CE等的几个近期实验中都可以触及。
We propose a scenario where a high scale seesaw origin of light neutrino mass and gravitational dark matter (DM) in MeV-TeV ballpark originating from primordial black hole (PBH) evaporation can be simultaneously probed by future observations of stochastic gravitational wave (GW) background with multiple tilts or spectral breaks. A high scale breaking of an Abelian gauge symmetry ensures the dynamical origin of the seesaw scale while also leading to the formation of cosmic strings responsible for generating stochastic GW background. The requirement of a correct DM relic in this ballpark necessitates the inclusion of a diluter as PBH typically leads to DM overproduction. This leads to a second early matter dominated epoch after PBH evaporation due to the long-lived diluter. These two early matter dominated epochs, crucially connected to the DM relic, lead to multiple spectral breaks in the otherwise scale-invariant GW spectrum formed by cosmic strings. We find interesting correlations between DM mass and turning point frequencies of GW spectrum which are within reach of several near future experiments like LISA, BBO, ET, CE, etc.
