Measurement of the phase between strong and electromagnetic amplitudes in the decay $J / ψ \to ϕ η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +652

The first direct measurement of the relative phase between the strong and electromagnetic amplitudes for a $J / ψ$ decaying into a vector-pseudoscalar final state is performed using…

Observation of di-structures in $e^{+} e^{-} \to J / ψ X$ at center-of-mass energies around 3.773 GeV

M. Ablikim, M. N. Achasov, P. Adlarson +477

We report a measurement of the observed cross sections of the inclusive $J / ψ$ production in $e^{+} e^{-} \to J / ψ X$ based on 3.21 fb $^{- 1}$ of data accumulated at energies…
