Heavy and baryons in the quark model
E. Ortiz-Pacheco, R. Bijker, A. Giachino +1
In this contribution, we present a study of ground- and excited-state and baryons consisting of two strange quarks and a heavy charm or bottom quark. An analysis in the…
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…
Electromagnetic and weak decays of baryons in the unquenched quark model
Roelof Bijker, Gustavo Guerrero-Navarro, Emmanuel Ortiz-Pacheco
In this contribution, we discuss the electromagnetic and weak decays of baryons in the unquenched quark model and show that the observed discrepancies between the experimental data…
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…
