PRL: Strong evidence for nucleon resonances near 1900 MeV

Strong evidence for nucleon resonances near 1900 MeV - A. V. Anisovich, V. Burkert, M. Hadžimehmedović, D. G. Ireland, E. Klempt, V. A. Nikonov, R. Omerović, H. Osmanović, A. V. Sarantsev, J. Stahov, A. Švarc, and U. Thoma 

Data on the reaction $\gamma p \to K^+\Lambda$ from the CLAS experiments are used to derive the leading multipoles, E0+, M1-, E1+, and M1+, from the production threshold to 2180\,MeV in 24 slices of the invariant mass. The four multipoles are determined without any constraints. The multipoles are fitted using a multichannel L+P model which allows us to search for singularities and to extract the positions of poles on the complex energy plane in an almost model-independent method. The multipoles are also used as additional constraints in an energy-dependent analysis of a large body of pion and photo-induced reactions within the Bonn-Gatchina (BnGa) partial wave analysis. The study confirms the existence of poles due to nucleon resonances with spin-parity J^P = 1/2^-; 1/2^+, and 3/2^+ in the region at about 1.9\,GeV.


Bled 2017: Advances in hadronic resonances

Two members of our group were participants of Mini Workshop in Bled, Slovenia (July 2 - 9, 2017). The purpose of this workshop is to give the participants an opportunity to concentrate on problems of common interest and to enable focused, intense discussions on individual topics. Typically, every day three participants present their subjects in 40-minutes talks and are encouraged to propose specific problems to be worked out in detail during the Workshop, either jointly or in smaller groups. The number of participants is typically limited to about 20.
