Search for the Lepton Flavor Violation Process $J/\psi \to e\mu$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +361

We search for the lepton-flavor-violating decay of the $J/\psi$ into an electron and a muon using $(225.3\pm 2.8)\times 10^6$ $J/\psi$ events collected with the BESIII detector at the B…
