Unraveling the nature of the novel $T_{cs}$ and $T_{c s ˉ}$ tetraquark candidates

P. G. Ortega, D. R. Entem, F. Fernandez +1

Using proton-proton collisions at centre-of-mass energies $7$ , $8$ , and $13$ TeV, with a total integrated luminosity of $9 fb^{- 1}$ , the LHCb collaboration has performed am…

Nature of the doubly-charmed tetraquark $T_{cc}^{+}$ in a constituent quark model

Pablo G. Ortega, Jorge Segovia, David R. Entem +1

The recently discovered $T_{cc}^{+}$ is evaluated as a $D D^{*}$ molecular structure in the $J^{P} = 1^{+}$ sector. A coupled-channels calculation in charged basis, considering the $D^0D^{*\,…

Strange hidden-charm $P_{ψ s}^{Λ} (4459)$ and $P_{ψ s}^{Λ} (4338)$ pentaquarks and additional $P_{ψ s}^{Λ}$ , $P_{ψ s}^{Σ}$ and $P_{ψ ss}^{N}$ candidates in a quark model approach

Pablo G. Ortega, David R. Entem, Francisco Fernandez

Hidden-charm pentaquark-like $P_{ψ s}^{Λ} (4459)^{0}$ and $P_{ψ s}^{Λ} (4338)$ resonances are studied in a constituent quark model as molecular meson-baryon structures. Such states are found…

The $Z_{cs} (3985)^{-}$ structure in a coupled-channels model

Pablo G. Ortega, David R. Entem, Francisco Fernandez

The discovery of the $Z_{c} (3900)^{\pm}$ and $Z_{b} (10610)^{\pm}$ structures in the heavy quarkonium spectrum showed the need to incorporate hadron structures beyond the naive $q q q$ and $q…

Does the $J^{P C} = 1^{+-}$ counterpart of the $X (3872)$ exist?

Pablo G. Ortega, David R. Entem, Francisco Fernandez

We explore the possible existence of the $J^{P C} = 1^{+-}$ counterpart of the $X (3872)$ state in a coupled-channels calculation within a constituent quark model, with the aim of conf…

The $D_{s 0} (2590)^{+}$ as the dressed $c s ˉ (2^{1} S_{0})$ meson in a coupled-channels calculation

Pablo G. Ortega, Jorge Segovia, David R. Entem +1

The recent discovery of the $D_{s 0} (2590)^{+}$ meson by the LHCb Collaboration has stimulated the analysis of meson-meson channels effects in the two-body quark-antiquark meson spect…
