论文摘要
我们提出了一个场景，即通过对称性恢复在通货膨胀期间，可以通过对称性恢复的一阶相变产生超重量的暗物质（DM）。相变发生在与充气场相连的观众扇区中。在相换过程中，观众场隧道从对称性破裂真空到对称性 - 恢复的真空吸尘器。气泡碰撞后产生的巨大颗粒受到恢复对称性的腐烂保护，并可以作为宇宙后来进化的DM候选者。我们表明，在相变期间释放的潜热足以产生今天观察到的DM遗物丰度。此外，与超重DM相伴，该一阶相变的还会产生可通过未来重力波检测器检测到的引力波。
We propose a scenario where superheavy dark matter (DM) can be produced via symmetry restoration first-order phase transition during inflation triggered by the evolution of the inflaton field. The phase transition happens in a spectator sector coupled to the inflaton field. During the phase transition, the spectator field tunnels from a symmetry-broken vacuum to a symmetry-restored vacuum. The massive particles produced after bubble collisions are protected against decaying by the restored symmetry and may serve as a DM candidate in the later evolution of the Universe. We show that the latent heat released during the phase transition can be sufficient to produce the DM relic abundance observed today. In addition, accompanied with the super heavy DM, this first-order phase transition also produces gravitational waves detectable via future gravitational wave detectors.
