论文摘要
在本次演讲中，我们通过在一环级别整合了三个右撇子中微子，将SEESAW模型的完整一环匹配的结果介绍到其低能的有效理论上。我们发现，在华沙有31个独立的Dimension-6（DIM-6）操作员（禁止风味结构和Hermitian coogates），标准模型耦合以及Weinberg Operator的Wilson系数在一环级别获得阈值校正。在单循环水平上达到DIM-6的完整Lagrangian被得出了，这是必不可少的，对于低能量下沉重的右手中微子的影响一致。
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.
