The structure in a coupled-channels model
Pablo G. Ortega, David R. Entem, Francisco Fernandez
The discovery of the and structures in the heavy quarkonium spectrum showed the need to incorporate hadron structures beyond the naive and $q…
Does the counterpart of the exist?
Pablo G. Ortega, David R. Entem, Francisco Fernandez
We explore the possible existence of the counterpart of the state in a coupled-channels calculation within a constituent quark model, with the aim of conf…
The as the dressed meson in a coupled-channels calculation
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
The recent discovery of the meson by the LHCb Collaboration has stimulated the analysis of meson-meson channels effects in the two-body quark-antiquark meson spect…
Renormalization of NN Chiral EFT, my personal mixed feelings
D. R. Entem
We are celebrating thirty-years from the seminal papers from Weinberg proposing to use the rules of Chiral Perturbation Theory to nucleon systems. His proposal was to build an Effe…
Symmetries, partners and thresholds: the case of the
Pablo G. Ortega, David R. Entem, Francisco Fernandez
The discovery of the meant the revival of the heavy meson spectroscopy beyond naive structures. Once that the scheme, which was very useful in the dawn…
Nucleon-nucleon potentials from Delta-full chiral effective-field-theory and implications
Y. Nosyk, D. R. Entem, R. Machleidt
We closely investigate NN potentials based upon the Delta-full version of chiral effective field theory. We find that recently constructed NN potentials of this kind, which (when a…
