论文摘要
我们研究了在近乎小型的超对称标准模型中，该模型的较大强子对撞机（LHC）可能会出现Sneutrino对的位移特征，该模型补充了右手中微子，从而触发了I型Seesaw机制。我们展示了如何在sneutrinos的Leptonic和Hadroonic衰减的情况下通过重型Higgs门户网站建立此类签名。我们最终说明了如何从与相应的两个位移顶点有关的运动学数量中提取后者的Yukawa参数，从而表征了中微子质量产生的基本机制的动力学。我们显示了当前和高光度LHC的情况下的数值结果。
We study displaced signatures of sneutrino pairs potentially emerging at the Large Hadron Collider (LHC) in a Next-to-Minimal Supersymmetric Standard Model supplemented with right-handed neutrinos triggering a Type-I seesaw mechanism. We show how such signatures can be established through a heavy Higgs portal in the presence of both leptonic and hadronic decays of the sneutrinos. We finally illustrate how the Yukawa parameters of the latter can be extracted from fitting kinematical quantities pertaining to the corresponding two displaced vertices, thereby characterising the dynamics of the underlying mechanism of neutrino mass generation. We show our numerical results for the case of both the current and High-Luminosity LHC.
