Electromagnetic couplings of pentaquarks
E. Ortiz-Pacheco, R. Bijker
In this contribution, we discuss the electromagnetic couplings of pentaquark states with hidden charm. This work is motivated by recent experiments at CERN by the LHCb Collaboraton…

The -puzzle solved by means of spectrum and strong decay amplitude predictions
E. Santopinto, A. Giachino, J. Ferretti +4
The observation of new states by LHCb \cite{Aaij:2017nav} and the confirmation of four of them by Belle \cite{Yelton:2017qxg} may represent an important milestone in ou…

Baryon spectroscopy in the unquenched quark model
Roelof Bijker, Gustavo Guerrero-Navarro, Emmanuel Ortiz-Pacheco
We discuss some applications of the unquenched quark model which is an extension of the CQM that includes the effects of sea quarks via a 3P0 quark-antiquark pair-creation mechanis…
