AbstraktAbstract

A search for a new Z' gauge boson predicted by L-mu - L-tau models, based on charged-current Drell-Yan production, pp -> W-+/-(*) -> Z'mu(+/-)nu -> mu(+/-)mu(-/+)mu(+/-)nu, is presented. The data sample used corresponds to an integrated luminosity of 140 fb(-1) of proton-proton collisions at root s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. The search examines a final state of 3 mu plus large missing transverse momentum. Upper limits are set on the Z' production cross section times branching ratio in the mass range of 5-81 GeV. After combining with the previous Z' search using the neutral-current Drell-Yan production with a 4 mu final state, the most stringent exclusion limits to date are achieved in the parameter space of the Z' coupling strength and mass.
