Statistical Inference of Scattering Parameters for Exotic Hadronic States in the Spectrum
André Aimé Atangana Likéné, P. Pradyun Hebbar, Alexis Franck Rothen +5
We present a global two-channel Flatté amplitude analysis of the hidden-charm pentaquark candidates observed by the LHCb collaboration in the J/ψp invariant-mass spectrum using the…
