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…
