具有一个$L$破坏耦合的超对称性中的轻子生成

Leptogenesis in supersymmetry with one $L$ violating coupling

Rathin Adhikari, Arnab Dasgupta

摘要:

我们已经展示了一个新的情况下,成功leptogenesis与一个$L$违反耦合和一个相对马约拉纳阶段发挥作用的$CP$违反。这与通常考虑至少有两个$L$违反耦合的费曼图相反。我们考虑了TeV尺度下超核发生的$R$ -宇称破坏最小超对称标准模型(MSSM).如果不对称性是通过半轻子$λ^{\prime}$耦合产生的,这种情况也与产生轻中微子质量相一致。

英文摘要:

We have shown a new scenario of successful leptogenesis with one $L$ violating coupling and a relative Majorana phase playing the role of $CP$ violation. This is in contrast to the usual consideration of Feynman diagram with at least two $L$ violating couplings. We have considered $R$-parity violating Minimal Supersymmetric Standard Model (MSSM) for leptogenesis at TeV scale. This scenario is also consistent with generating light neutrino mass if asymmetry is generated through semileptonic $λ^{\prime}$ coupling.
