P. S. Bhupal Dev, Peter Millington, Apostolos Pilaftsis, Daniele Teresi

摘要:

我们修正了Nucl.Phys.B886(2014)569 [1]中关于那里考虑的数值例子的不正确讨论。特别是,我们讨论了共振Leptogenesis的最小辐射模型的可行性,并证明在这些情况下,没有不对称可以产生在$\mathcal{O}(h^4)$。我们提出了一个最小的修改模型考虑在[1]中,电弱尺度右手Majorana中微子可以很容易地容纳成功的leptogenesis和可观察到的签名在轻子数和味破坏实验。本文再次证实了文[1]中提出的全味协变速率方程对于精确描述轻子不对称性的产生的重要性。

英文摘要:

We amend the incorrect discussion in Nucl. Phys. B 886 (2014) 569 [1] concerning the numerical examples considered there. In particular, we discuss the viability of minimal radiative models of Resonant Leptogenesis and prove that no asymmetry can be generated at $\mathcal{O}(h^4)$ in these scenarios. We present a minimal modification of the model considered in [1], where electroweak-scale right-handed Majorana neutrinos can easily accommodate both successful leptogenesis and observable signatures at Lepton Number and Flavour Violation experiments. The importance of the fully flavour-covariant rate equations, as developed in [1], for describing accurately the generation of the lepton asymmetry is reconfirmed.
