Exploration of the LHCb $P_c$ 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 ${\bar{D}}^{(\ast )}{\Lambda }_c-{\bar{D}}^{(\ast )}{\Sigma }_c^{(\ast )}$ within an analytic, unitary, coupled-channel approach by including the $J/\psi p$ chann…
