Probing hidden leptonic scalar portals using the NA64 experiment at CERN

Abstract In this study, we demonstrate the potential of the NA64 experiment at CERN SPS to search for New Physics processes involving $$e\rightarrow \mu $$ e → μ transitions after the collision of 100 GeV electrons with target nuclei. A new Dark Sector leptonic portal in which a scalar boson $$\varp...
