The charged current production of long-lived heavy neutrinos at the LHC can use a prompt charged lepton for triggering the measurement of the process. However, in order to fully characterize the heavy neutrino interactions, it is necessary to also probe Higgs or Z mediated neutral current production. In this case the charged lepton is not available, so other means of triggering are required. In this work, we explore the possibility of using a vector boson fusion trigger in the context of a GeV-scale Type I Seesaw model. We consider a minimal model, where both Higgs and Z-mediated contributions produce one heavy neutrino, as well as an extended model where the Higgs can decay into two heavy ones. Both scenarios are tested through displaced dilepton and displaced multitrack jet searches.A preprint version of the article is available at ArXiv.

使用VBF触发器在LHC上搜索长寿命的重中微子

大型强子对撞机中长寿命重中微子的带电电流产生可以使用迅速带电的轻子来触发过程的测量。但是，为了充分表征重中微子的相互作用，还必须探究希格斯或Z介导的中性电流产生。在这种情况下，带电的轻子不可用，因此需要其他触发方式。在这项工作中，我们探索了在GeV规模的I型跷跷板模型中使用矢量玻色子融合触发器的可能性。我们考虑一个最小模型，希格斯和Z介导的贡献产生一个重中微子，以及一个扩展模型，希格斯可以衰变成两个重中微子。两种情况都通过位移的双链飞船和位移的多轨喷射搜索进行了测试。该文章的预印本可从ArXiv获得。
