Search for a new Z′ gauge boson via the pp →W± (*) →z′μ±ν →μ∓μ μ±ν process in pp collisions at vs =13 TeV with the ATLAS detector

A search for a new Z gauge boson predicted by L-mu - L-tau models, based on charged-current Drell-Yan production, pp -> W-+/-(*()) -> Zmu(+/-)nu -> mu(+/-)mu(-/+)mu(+/-)nu, is presented. The data sample used corresponds to an integrated luminosity of 140
