论文摘要
在r-统计上的超对称性中，最轻的中性诺可能非常轻，甚至无质量。对于$ 500 $ MEV $ \ Lessim m _ {\tildeχ^0_1} \ Lessim 4.5 $ GEV的群众，可以通过违反r-Parity违反耦合的R-Parity在强子碰撞中产生Neutilino，随后衰减给打火机的Meson and Meson and Meson and Meson and Messon和A Permed Lepton。由于中性质量很小，并且对于违反耦合耦合的小r-偏见是长期寿命的，导致固定目标和对撞机实验的顶点流离失所。在这项工作中，我们在拟议的实验Anubis和LHC的MAPP上研究了此类特征。在这些情况下，我们还将其敏感性与其他当前和提议的实验（例如Atlas，codex-B和Mathusla）进行了比较。我们发现Anubis和Mapp可以表现出互补或优越的灵敏度。
In R-parity-violating supersymmetry the lightest neutralino can be very light, even massless. For masses in the range $500$ MeV$\lesssim m_{\tildeχ^0_1}\lesssim 4.5$ GeV the neutralino can be produced in hadron collisions from rare meson decays via an R-parity violating coupling, and subsequently decay to a lighter meson and a charged lepton. Due to the small neutralino mass and for small R-parity violating coupling the lightest neutralino is long-lived, leading to displaced vertices at fixed-target and collider experiments. In this work, we study such signatures at the proposed experiments ANUBIS and MAPP at the LHC. We also compare their sensitivity reach in these scenarios with that of other present and proposed experiments at the LHC such as ATLAS, CODEX-b, and MATHUSLA. We find that ANUBIS and MAPP can show complementary or superior sensitivity.
