Two strategies were pursued. The first is an inclusive approach which targets BSM scenarios with Z bosons produced |

in the decays of strongly-interacting particles. The second is a targeted approach which focuses on BSM scenarios |

|
where the Z bosons are produced in the decays of weakly-interacting particles. The main backgrounds are |
