论文摘要
我们考虑在最小的I型seesaw场景中，使用两个右手的单线中微子中微子$ n_ {1,2} $组成伪dirac对，集中在Pseudo-dirac对的情况下，以pseudo-dirac群体为pseudo-dirac对具有值的pseudo-dirac对$ _ {1,2} \ gev。在单个Lepton中违反CP违反不对称的情况时，研究了以$ 1 \ leftrightArrow 2 $ decay流程产生的宇宙的总Lepton Charge $ L $中的总和Lepton Charge $ L $。我们表明，对于$ m_ {1,2} $，在间隔$ m_ {1,2} =（0.3-100）$ gev中，成功的瘦化发生是可能的。我们的结果还特别表明，对于消除最初的$ n_ {1,2} $丰度，风味效应在生成Baryon不对称的产生中可以发挥重要作用，从而导致不对称的因素提高了最多$ \ sim 300 $的因素300 $，相对于“未氟化”的Lepteptogenseaseason方案。
We consider sub-TeV scale flavoured resonant leptogenesis within the minimal type-I seesaw scenario with two right-handed singlet neutrinos $N_{1,2}$ forming a pseudo-Dirac pair, concentrating on the case of masses of the pseudo-Dirac pair having values $M_{1,2} \lesssim 100$ GeV. The case when the CP violating asymmetries in the individual lepton charges $L_l$, $l=e,μ,τ$, and in the total lepton charge $L$ of the Universe are generated in $1 \leftrightarrow 2$ decay processes is investigated. We show that successful leptogenesis is possible for $M_{1,2}$ lying in the interval $M_{1,2} = (0.3 - 100)$ GeV. Our results show also, in particular, that for vanishing initial $N_{1,2}$ abundance, flavour effects can play an important role in the generation of the baryon asymmetry, leading to an enhancement of the asymmetry by a factor up to $\sim 300$ with respect to the "unflavoured" leptogenesis scenario.
