Exploration of the Muon $g-2$ and Light Dark Matter explanations in NA64 with the CERN SPS high energy muon beam

Yu. M. Andreev, D. Banerjee, B. Banto Oberhauser +54

We report on a search for a new $Z^{\prime }$ ($L_{\mu }-L_{\tau }$) vector boson performed at the NA64 experiment employing a high energy muon beam and a missing energy-momentum technique. Muons from…
