使用 LHCb 探测器在 7 TeV 和 8 TeV 处收集的 3.0 次质子-质子碰撞来搜索重的长寿命带电粒子。搜索主要基于环形成像切伦科夫探测器的响应，以区分重的、移动缓慢的粒子和μ介子。没有发现任何证据可以证明这种长寿状态的产生。结果表示为对长寿命粒子对的 Drell-Yan 产生的限制，这两个粒子都处于 LHCb 伪快速接受度中。对于 14 到 309 之间的质量，取决于质量的横截面上限在 2–4 fb（95% CL 时）范围内。
A search is performed for heavy long-lived charged particles using 3.0of proton–proton collisions collected at7 and 8 TeV with the LHCb detector. The search is mainly based on the response of the ring imaging Cherenkov detectors to distinguish the heavy, slow-moving particles from muons. No evidence is found for the production of such long-lived states. The results are expressed as limits on the Drell–Yan production of pairs of long-lived particles, with both particles in the LHCb pseudorapidity acceptance,. The mass-dependent cross-section upper limits are in the range 2–4 fb (at 95 % CL) for masses between 14 and 309.
