Threshold effects in P-wave bottom-strange mesons
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
Using a nonrelativistic constituent quark model in which the degrees of freedom are quark-antiquark and meson-meson components, we have recently shown that the thresh…
From to LHCb pentaquarks
F. Fernández, D. R. Entem, P. G. Ortega +1
The two exotic and discovered in by the LHCb Collaboration, together with the four resonances , , and , repo…
From to LHCb pentaquark
F. Fernández, D. R. Entem, P. G. Ortega +1
The original charmonium two-body problem, like the structure of the meson, has become more involved in the last few years with the discovery of new resonances such…
Flavour decomposition of electromagnetic transition form factors of nucleon resonances
Jorge Segovia, Craig D. Roberts
In Poincaré-covariant continuum treatments of the three valence-quark bound-state problem, the force behind dynamical chiral symmetry breaking also generates nonpointlike, interact…
Canonical description of the new LHCb resonances
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
The LHCb Collaboration has recently observed four structures called , , and in the decays. We study them herein us…
Dissecting nucleon transition electromagnetic form factors
Jorge Segovia, Craig D. Roberts
In Poincaré-covariant continuum treatments of the three valence-quark bound-state problem, the force behind dynamical chiral symmetry breaking also generates nonpointlike, interact…
Effective field theory investigations of the XYZ puzzle
Jorge Segovia
Quantum Chromodynamics, the theory of strong interactions, predicts several types of bound states. Among them are mesons () and baryons (), which have been the only…
Baryons and the Borromeo
Craig D. Roberts, Jorge Segovia
The kernels in the tangible matter of our everyday experience are composed of light quarks. At least, they are light classically; but they don't remain light. Dynamical effects wit…
Molecular components in P-wave charmed-strange mesons
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
Results obtained by various experiments show that the and mesons are very narrow states located below the and thresholds, resp…
Electrocouplings in Dyson-Schwinger Equations
Jorge Segovia
A symmetry preserving framework for the study of continuum Quantum Chromodynamics (QCD) is obtained from a truncated solution of the QCD equations of motion or QCD's Dyson-Schwinge…
Bottomonium spectrum revisited
Jorge Segovia, Pablo G. Ortega, David R. Entem +1
We revisit the bottomonium spectrum motivated by the recently exciting experimental progress in the observation of new bottomonium states, both conventional and unconventional. Our…
Elastic and Transition Form Factors in DSEs
Jorge Segovia
A symmetry preserving framework for the study of continuum Quantum Chromodynamics (QCD) is obtained from a truncated solution of the QCD equations of motion or QCD's Dyson-Schwinge…
