论文摘要

我们介绍了一个模型,其中暗物质(DM)和中微子质量的起源与标量单重线场的一阶相变相关。在阶段过渡期间,源右中微子(RHN)会动态地获取时空依赖性质量,其中一小部分是通过谐振振荡转化为一个非常弱的混合的深色RHN,它腐烂到了暗物质RHN,并带有观察到的Relic runcundance。中微子肿块是通过第四个RHN和源中微子之间传统的两种RHN型I型Seesaw产生的。相变期间产生的引力波的峰值频率随DM质量的增加而增加,并且在未来的重力波干涉仪中可检测到〜1 MeV的DM质量。由于源RHNS比Electroweak量表重,因此也可以实现成功的瘦素发生。

We introduce a model in which the genesis of dark matter (DM) and neutrino masses is associated with a first order phase transition of a scalar singlet field. During the phase transition a source right-handed neutrino (RHN) acquires a spacetime-dependent mass dynamically, a small fraction of which is converted via resonant oscillations into a very weakly mixed dark RHN which decays to a dark matter RHN with the observed relic abundance. Neutrino masses are generated via a traditional two RHN type-I seesaw between a fourth RHN and the source neutrino. The gravitational waves produced during the phase transition have a peak frequency that increases with the DM mass, and are detectable at future gravitational wave interferometers for DM masses above ~ 1 MeV. Since the source RHNs are heavier than the electroweak scale, successful leptogenesis is also attainable.
