Holly Pacey and the Half-Spin Particles: Searching for new physics with leptons at the ATLAS experiment
… 80.5 fb⁻¹ and the full 139.5 fb⁻¹ of the ATLAS Run 2 dataset, respectively. The first search placed the first ATLAS Run 2 limits on chargino pair production decaying via W-bosons, excluding chargino masses up to 410 GeV for a massless neutralino. This was surpassed by the second search, …
