论文摘要
搜索了charginos的Electroweak对生产以及Chargino和Neutralino的相关生产，每种都会通过$ r $ - Parity-Parity-Parity-Parity-Parity-Parity-Parity-actity耦合到Lepton和$ W $，$ Z $或Higgs Boson。 Trilepton不变性质量光谱是由带有三个或三个或以上的叶子的事件构建的，其目标是chargino衰变，其中包括电子或穆恩和leptonity腐烂的$ z $ boson。分析的数据集对应于139 fb $^{ - 1} $的集成亮度，由大型强子撞机在$ \ sqrt {s} $ = 13 tev的质量中心能量中产生的质子 - 普罗顿碰撞数据对应，并与2015年和2018年之间的Atlas实验收集。该结果被解释为在标准模型以外的过程中，在模型独立的横截面上的置信水平为95％的限制。对于最小的超对称标准模型的Charginos和Neutmtrinos的生产也设定了限制，该模型具有大约$ b $ -L $ $ symmetry。 Charginos和Neutmaros具有100 GEV至1100 GEV之间的质量，具体取决于假定的衰减分支分支的分支（电子，Muon或$τ$ -Lepton）加上Boson（$ W $，$ Z $或HIGGS）。
A search is performed for the electroweak pair production of charginos and associated production of a chargino and neutralino, each of which decays through an $R$-parity-violating coupling into a lepton and a $W$, $Z$, or Higgs boson. The trilepton invariant-mass spectrum is constructed from events with three or more leptons, targeting chargino decays that include an electron or muon and a leptonically decaying $Z$ boson. The analyzed dataset corresponds to an integrated luminosity of 139 fb$^{-1}$ of proton-proton collision data produced by the Large Hadron Collider at a center-of-mass energy of $\sqrt{s}$ = 13 TeV and collected by the ATLAS experiment between 2015 and 2018. The data are found to be consistent with predictions from the Standard Model. The results are interpreted as limits at 95% confidence level on model-independent cross sections for processes beyond the Standard Model. Limits are also set on the production of charginos and neutralinos for a Minimal Supersymmetric Standard Model with an approximate $B$-$L$ symmetry. Charginos and neutralinos with masses between 100 GeV and 1100 GeV are excluded depending on the assumed decay branching fractions into a lepton (electron, muon, or $τ$-lepton) plus a boson ($W$, $Z$, or Higgs).
