• Baryon resonances in J/$$\mathbf{\psi}$$ decays
High statistics BESIII data on the decays $$J/\psi \to p \bar p \pi^0/p \bar p\eta$$ and $$J/\psi (\psi^\prime) \to \bar p n \pi^+ / p \bar n \pi^-$$will allow us to independently confirm resonance properties determined from photoproduction data. This is an important task especially in the case of new high mass states as well as in case of the Roper-resonance, whose dynamical origin is still intensely discussed. We plan to reconstruct these decays using the full available statistics of the $$J/\psi$$ and $$\psi^\prime$$datasets from BESIII and to perform an amplitude analysis for the interpretation.
