Nature of the states from compositeness criteria
Yu-Fei Wang, Chao-Wei Shen, Deborah Rönchen +3
Based on a coupled-channel approach, we investigate the structures of four states through compositeness criteria. Toward a more precise description of the states, we have obt…
Box Singularity Conditions in Box Diagrams of Decay Processes
Chao-Wei Shen, Ming-Yang Duan, Jia-Jun Wu
Since 1959, singularities within single-loop diagrams have been studied. They are believed to significantly influence our understanding of experimental observables. In this study,…
Exploration of the LHCb states and possible resonances in a unitary coupled-channel model
Chao-Wei Shen, Deborah Rönchen, Ulf-G. Meißner +2
We extend our previous study of the interactions of within an analytic, unitary, coupled-channel approach by including the chann…
Nature of the and resonances via coupled-channel dynamics
Yu-Fei Wang, Ulf-G. Meißner, Deborah Rönchen +1
This work aims at determining the composition of certain and resonances, i.e. whether they are compact states formed directly by quarks and gluons, or hadronic molecules…
Light baryon resonances from a coupled-channel study including photoproduction
Deborah Rönchen, Michael Döring, Ulf-G. Meißner +1
The Jülich-Bonn dynamical coupled-channel approach is extended to include photoproduction off the proton. Differential cross section and (double) polarization data for $K^+Σ^0…
Resonances in heavy meson - heavy baryon coupled-channel interactions
Zheng-Li Wang, Chao-Wei Shen, Deborah Rönchen +2
The interactions of are studied within the framework of a dynamical coupled-channel approach. A series of bound states and resonances w…
