论文摘要
在最小的左右对称模型的背景下，我们研究了当前和未来的中性s中性双β（$0νβ$）衰减实验之间的相互作用，LHC主要检测器Atlas/cms的长期粒子搜索以及拟议的远处检测器Mathusla。可以与从$ W $ boson的衰减中的电子相关的繁重的主要中微子，用于非零左右混合，随后衰减到另一个具有相同电荷和喷气机的电子中。由于抑制了大型右手带电量表boson $ w_r $质量，重型中微子可能会长期存在。我们表明，在LHC处的同一符号DILEPTON通道中，长期存在的粒子（LLP）搜索可用于扩展$ W_R $ BOSON质量相对于Keung-Senjanovic（KS）过程的范围。最后，我们表明，在高光度LHC上使用主要检测器ATLAS/CMS的LLP搜索的敏感性与未来$0νβ.$衰减搜索的敏感性具有竞争力。
In the context of the minimal left-right symmetric model, we study the interplay between current and future neutrinoless double beta ($0νββ$) decay experiments, long-lived particle searches at the LHC main detectors ATLAS/CMS, and the proposed far detector MATHUSLA. The heavy Majorana neutrino can be produced in association with an electron from the decay of $W$ boson for a non-zero left-right mixing and subsequently decays into another electron with the same charge and jets. Owing to the suppression of large right-handed charged gauge boson $W_R$ mass, the heavy neutrinos could be long-lived. We show that long-lived particle (LLP) searches for heavy Majorana neutrinos in the same-sign dilepton channel at the LHC can be used to extend $W_R$ boson mass reach relative to the reach of the Keung-Senjanovic (KS) process. Finally, we show that sensitivities of LLP searches at the high-luminosity LHC with main detectors ATLAS/CMS are competitive with those of future $0νββ$ decay searches.
