The $T_{c s ˉ} (2900)$ as a threshold effect from the interaction of the $D^{} K^{}$ , $D_{s}^{*} ρ$ channels

R. Molina, E. Oset

We investigate the $D^{*} K^{*}$ and $D_{s}^{*} ρ$ interaction in coupled channels within the hidden gauge formalism. A structure is developed around their thresholds, short of producing a b…

Two states for the $Ξ (1820)$ resonance

R. Molina, Wei-Hong Liang, Chu-Wen Xiao +2

We recall that the chiral unitary approach for the interaction of pseudoscalar mesons with the baryons of the decuplet predicts two states for the $Ξ (1820)$ resonance, one with a n…

Theoretical interpretation of the $Ξ (1620)$ and $Ξ (1690)$ resonances seen in $Ξ_{c}^{+} \to Ξ^{-} π^{+} π^{+}$ decay

Hai-Peng Li, Gong-Jie Zhang, Wei-Hong Liang +1

We study the Belle reaction $Ξ_{c}^{+} \to Ξ^{-} π^{+} π^{+}$ looking at the mass distribution of $π^{+} Ξ$ , where clear signals for the $Ξ (1620)$ and $Ξ (1690)$ resonances are seen. These two…

Inverse problem in femtoscopic correlation functions: The $T_{cc} (3875)^{+}$ state

M. Albaladejo, A. Feijoo, I. Vidaña +2

We study here the inverse problem of starting from the femtoscopic correlation functions of related channels and analyze them with an efficient tool to extract the maximum informat…

Evolution of compact states to molecular ones with coupled channels: The case of the $X (3872)$

Jing Song, L. R. Dai, E. Oset

We study the molecular probability of the $X (3872)$ in the $D^{0} D ˉ^{* 0}$ and $D^{+} D^{*-}$ channels in several scenarios. One of them assumes that the state is purely due to a g…

Evolution of genuine states to molecular ones: The $T_{cc} (3875)$ case

L. R. Dai, J. Song, E. Oset

We address the issue of the compositeness of hadronic states and demonstrate that starting with a genuine state of nonmolecular nature, but which couples to some meson-meson compon…
