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…
Lowest lying even-parity mesons: heavy quark spin-flavor symmetry, chiral dynamics, and constituent quark model bare masses
Miguel Albaladejo, Pedro Fernandez-Soler, Juan Nieves +1
The discovery of the and resonances in the charmed-strange meson spectra revealed that formerly successful constituent quark models lose predicta…
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…
Molecular components in and mesons
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
Different experiments have confirmed that the and mesons are very narrow states located, respectively, below the and threshold…
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…
LHCb pentaquarks in constituent quark models
P. G. Ortega, D. R. Entem, F. Fernández
The recently discovered and states at LHCb have masses close to the and thresholds, respectively, which suggest that they ma…
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…
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…
Partners of the and HQSS breaking
D. R. Entem, P. G. Ortega, F. Fernandez
Since the discovery of the the study of heavy meson molecules has been the subject of many investigations. On the experimental side different experiments have looked for…
