论文摘要
最近，人们对以更加限制的方式探索宇宙的黑暗部门产生了新的兴趣。特别是在[1]中，fi夫（微弱相互作用的大量粒子）场景被证明是通过在νmsm精神上用三个无菌中微子的SM延伸而实现的。在本文中，我们表明，在不调用模型的任何其他对称性的情况下，我们可以意识到ADM（非对称暗物质）在可见的和深色扇区中信号的Matter-Arti-Matter不对称的常见起源。该模型允许通过类型I SEESAW机制具有正确的活跃中微子质量的一系列暗物质质量，具有正确的主动中微子质量。因此，该模型解释了中微子的质量，暗物质丰度，并在黑暗部门中复制了可见扇区的物质 - 抗对称不对称，所有这些都在νmsm的版本中。黑暗部门中的不对称性体现在共同中微子在共同框架中的一个平等性的优势，这在正在进行的实验中应该是可以确定的。
Recently there is a renewed interest in exploring the Dark sector of the universe in a more constrained way. Particularly in [1], the FIMP ( Feebly Interacting Massive Particle) scenario was shown to be realized with a minimal extension of the SM with three sterile neutrinos in the spirit of νMSM. In this paper, we show that without invoking any additional symmetries of the model, we can realize the idea of ADM (Asymmetric Dark Matter) signaling a common origin of the matter-anti-matter asymmetries in visible as well as Dark sectors. The model allows for a range of dark matter masses, 1 - 100keV, with correct active neutrino masses through the Type-I seesaw mechanism. Thus, the model explains the neutrino masses, Dark Matter abundance and replicates matter-anti-matter asymmetry of the visible sector in the Dark sector, all in a version of the νMSM. The asymmetry in the dark sector is manifested in the predominance of one parity of the heavy neutrinos in the comoving frame, which should be determinable in the ongoing experiments.
