We present a purely linear seesaw mechanism in a mirror left-right symmetric framework and then realize a novel leptogenesis scenario for parametrizing the cosmic baryon asymmetry by the charged lepton masses, the light Majorana neutrino mass matrix and the heavy mirror charged lepton masses. Through the same Yukawa couplings, the lepton-number-conserving decays of the mirror charged leptons can generate three individual lepton asymmetries stored in the ordinary lepton flavors, while the lepton-number-violating processes for the Majorana neutrino mass generation can wash out part of these lepton asymmetries. The remnant lepton asymmetries then can be partially converted to a baryon asymmetry by the sphaleron processes.

我们在镜像左右对称框架中提出了一种纯粹的线性跷跷板机制，然后实现了一种新的瘦子生成方案，用于通过带电的轻子质量，轻的马约拉纳中微子质量矩阵和重的镜带电的轻子质量来参数化宇宙重子的不对称性。通过相同的Yukawa偶合，带镜电荷的轻子的保持轻子数的衰变可以产生存储在普通轻子风味中的三个单独的轻子不对称性，而产生马约拉纳中微子质量的违反轻子数的过程可以洗掉一部分轻子。这些轻子不对称。然后，剩余的轻子不对称性可以通过sphaleron过程部分转化为重子不对称性。
