Measurement of the branching fraction of the decay J/ψ\to p \bar{p} η

A high precision measurement of the branching fraction of the decay J/\psi \to p \bar{p} \eta is performed using (10 087 \pm 44) \times 10^6 J/\psi events recorded by the {BESIII} detector at the {BEPCII} storage ring. The branching fractions of the two decays $J/\psi \to p \bar{p} \eta(\eta \to... Show more
