$1 \leftrightarrow 2$ Processes of a Sterile Neutrino Around Electroweak Scale in the Thermal Plasma

Xue-Min Jiang, Yi-Lei Tang, Zhao-Huan Yu, Hong-Hao Zhang

摘要:

本文应用Goldstone等效规范计算了标准模型(SM)临界温度以下的热等离子体中无菌中微子的$1 \leftrightarrow 2$过程$T_c \approx 160 \text{ GeV}$。无菌中微子的质量在电弱标度$50 \text{ GeV} \leq m_N \leq 200 \text{ GeV}$附近,获得的热平均有效宽度$\barΓ_{\text{tot}}$在交叉点附近是连续的。我们也将应用我们的结果来执行leptogenesis的初步计算。

英文摘要:

In this paper, we will apply the Goldstone equivalence gauge to calculate the $1 \leftrightarrow 2$ processes of a sterile neutrino in the thermal plasma below the standard model (SM) critical temperature $T_c \approx 160 \text{ GeV}$. The sterile neutrino's mass is around the electroweak scale $50 \text{ GeV} \leq m_N \leq 200 \text{ GeV}$, and the acquired thermal averaged effective width $\barΓ_{\text{tot}}$ is continuous around the cross-over. We will also apply our results to perform a preliminary calculation of the leptogenesis.
