跷跷板模型的单圈匹配

One-loop Matching for the Seesaw Model

Di Zhang, Shun Zhou

摘要:

在这次演讲中,我们提出了完整的单圈匹配的跷跷板模型到其低能量有效理论的结果,通过整合出三个右手中微子在单圈水平。我们发现,有31个独立的6维(dim-6)运营商(禁止味结构和厄米共轭)在华沙基础上,和标准模型耦合和威尔逊系数的温伯格运营商获得阈值校正在一个循环的水平。在单圈水平上导出了dim-6的完整的拉格朗日量,这对于一致地探索低能重右手中微子的碰撞是必不可少的。

英文摘要:

In this talk, we present the results of the complete one-loop matching of the seesaw model onto its low-energy effective theory by integrating out three right-handed neutrinos at the one-loop level. We find that there are 31 independent dimension-6 (dim-6) operators (barring flavor structures and Hermitian conjugates) in the Warsaw basis, and the standard-model couplings and the Wilson coefficient of the Weinberg operator acquire threshold corrections at the one-loop level. The complete Lagrangian up to dim-6 at the one-loop level is derived, which is indispensable for consistent explorations of the impact of heavy right-handed neutrinos at low energies.
