Strong evidence for nucleon resonances near 1900\,MeV

A. V. Anisovich, V. Burkert, M. Hadžimehmedović +9

Data on the reaction $γ p \to K^{+} Λ$ from the CLAS experiments are used to derive the leading multipoles, $E_{0 +}$ , $M_{1 -}$ , $E_{1 +}$ , and $M_{1 +}$ , from the production threshold to…

$N^{*}$ resonances from $K Λ$ amplitudes in sliced bins in energy

A. V. Anisovich, V. Burkert, M. Hadžimehmedović +8

The two reactions $γ p \to K^{+} Λ$ and $π^{-} p \to K^{0} Λ$ are analyzed to determine the leading photoproduction multipoles and the pion-induced partial wave amplitudes in slices of the inv…

$N^{*} \to N η^{'}$ decays from photoproduction of $η^{'}$ -mesons off protons

A. V. Anisovich, V. Burkert, P. M. Collins +6

A study of the partial-wave content of the $γ p \to η^{'} p$ reaction in the fourth resonance region is presented, which has been prompted by new measurements of polarization obse…

Is there a narrow $N (1685)$ ?

A. V. Anisovich, V. Burkert, E. Klempt +3

The helicity-dependent observable $E$ for the reaction $γ d \to η n (p)$ with a spectator proton was recently measured by the A2 Collaboration at MAMI in Mainz. The data were interpre…
