论文摘要
在这项工作中,我们证明,以前被认为是涉及两个右手的主要中微子的重子不对称机制的不同机制,其质量远低于肠道量表 - 通过中微子振荡和谐振瘦瘦的生成的瘦素发生 - 实际上是团结的。我们表明,可以为所有实验允许的中微子质量的值生成观察到的重子不对称的值,高于$ m_n \ gtrsim 100 $ MEV。卵生成在广泛的参数中有效,包括在两个右手中微子之间分裂的质量,高达$Δm_n/m_n \ sim 0.1 $,以及在较大的较大和轻度中微子之间混合角度,足以可访问足够大的较大的中微子,以至于可以易于访问计划的强度实验或将来的截面。
In this work we demonstrate that what was previously considered as different mechanisms of baryon asymmetry generation involving two right-handed Majorana neutrinos with masses far below the GUT scale -- leptogenesis via neutrino oscillations and resonant leptogenesis -- are actually united. We show that the observed baryon asymmetry can be generated for all experimentally allowed values of the right-handed neutrino masses above $M_N \gtrsim 100$ MeV. Leptogenesis is effective in a broad range of the parameters, including mass splitting between two right-handed neutrinos as big as $ΔM_N/M_N \sim 0.1$, as well as mixing angles between the heavy and light neutrinos large enough to be accessible to planned intensity experiments or future colliders.
