摘要

本文利用大型强子对撞机的Run-2数据，得到了类矢量轻子衰变成标准模型规范玻色子和第二代轻子对产生的电流限制。由于没有专门的Run-2数据搜索，我们在多轻子通道中搜索iii型跷跷板重轻子，从而对ATLAS分析进行了重新定义。SU(2) L单重态类矢量轻子在100 GeV左右没有极限，而双重态类矢量轻子在780 GeV左右有极限。因此，专门寻找类矢量轻子是必要的，特别是对于单重态轻子。我们还研究了类矢量轻子衰变的一般情况和在HL-LHC上的未来灵敏度。

Current status on pair-produced muon-philic vectorlike leptons in multilepton channels at the LHC

A bstract In this work, we obtain the current limits on the pair production of vectorlike leptons decaying to a Standard Model gauge boson and a lepton in the second generation using the Run-2 data at the LHC. Since there is no dedicated search out of Run-2 data, we recast the ATLAS analyses searching for the type-III seesaw heavy leptons in the multi-lepton channels. There is no limit for the SU(2) L singlet vectorlike lepton beyond about 100 GeV, while the limit is about 780 GeV for the doublet one. Thus, dedicated searches for the vectorlike leptons are necessary, especially for the singlet one. We also study the general cases of the vectorlike lepton decays and future sensitivities at the HL-LHC.

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
