Measurement of the branching fraction of the decay $J/\psi \to p\bar{p}\eta$

BESIII Collaboration, M. Ablikim, M. N. Achasov +645

A high precision measurement of the branching fraction of the decay $J/\psi \to p\bar{p}\eta$ is performed using $(10087\pm 44)\times 10^6$ $J/\psi$ events recorded by the {BESIII} dete…
