计量B-L Leptogenesis

Gauged B-L Leptogenesis

Yuji Kajiyama, Shaaban Khalil, Hiroshi Okada, Ernest Ma

摘要:

我们提出了一个新的leptogenesis方案规范$B-L$模型与超对称性在TeV的能量尺度。我们不再依赖于单线态中微子$N^c$的非常小的汤川耦合来产生所观测到的宇宙重子不对称性(这需要非常大的共振增强),而是调用了它们的$B-L$规范相互作用。如果一个特定的标量双线性$\tilde N^c \tilde N^c$项不被允许,则成功的leptogenesis是可能的。

英文摘要:

We propose a new leptogenesis scenario in a gauged $B-L$ model with supersymmetry at the TeV energy scale. Instead of relying on the very small Yukawa couplings of the singlet neutrinos $N^c$ to generate the observed baryon asymmetry of the Universe, which requires a very large resonance enhancement, their $B-L$ gauge interactions are invoked. Successful leptogenesis is then possible if a particular scalar bilinear $\tilde N^c \tilde N^c$ term is disallowed.
