The project is well synchronised with the start of the LHC Run-3, which will lead to the collection of unprecedented amounts of proton-proton collisions at the highest energies ever reached at a collider. The project is part of Sussex's leading programme of data-intensive searches for new physics phenomena Beyond the Standard Model (BSM) in multileptonic final states at ATLAS, using Run-2 and Run-3 data samples collected by the experiment. Multileptonic "signatures" are characteristic of a wide range of exciting BSM scenarios, which aim to shed light on some of the most pressing questions in fundamental physics - such as the origin of dark matter in our universe, or the fundamental nature of neutrino masses. Models to be explored include the production of weakly interacting supersymmetric particles known as charginos and neutralinos, or the production of exotic heavy neutral leptons as encountered in seesaw models of neutrino masses.Sussex's principal technical involvement in ATLAS is through the experiment's trigger system, including focus on future upgrades of the ATLAS detector. Commensurately with their role, and in synergy with their other research and training activities, the student will contribute to Sussex's technical commitments to the ATLAS experiment. Example of trigger-related activities that Sussex students have significantly contributed to in recent years include software developments for the ATLAS Inner Detector system, or the characterisation of key properties of electron-based triggers.

该项目与LHC Run-3的开始很好地同步，这将导致在有史以来最高能量的撞机碰撞器中收集了前所未有的质子 - 质子碰撞。该项目是使用实验收集的Run-2和Run-3数据样本，在Atlas的多雌性最终状态下，在ATLAS多雌性最终状态下对新物理现象进行数据密集型搜索计划的领先计划的一部分。多雌性“签名”是各种令人兴奋的BSM场景的特征，旨在阐明一些基本物理学中一些最紧迫的问题，例如我们宇宙中暗物质的起源或中性群体的基本性质。要探索的模型包括生产弱相互作用的超对称颗粒，称为charginos和中性粒子，或产生异国情调的重型中性瘦素，如中微子群众的SeeSAW模型中所遇到的。Sussex在Atlas中的主要技术参与是通过实验的触发系统，包括将来的触发器系统，包括将来的Upgrade of the Atlas Atlas detector。与他们的角色以及与其他研究和培训活动的协同作用，学生将为苏塞克斯对Atlas实验的技术承诺做出贡献。近年来，苏塞克斯学生对触发相关活动的示例包括Atlas内部检测器系统的软件开发，或基于电子触发器的关键特性的表征。
