Unveiling the $K_{1} (1270)$ double-pole structure in the $B ˉ \to J / ψ ρ K ˉ$ and $B ˉ \to J / ψ K ˉ^{*} π$ decays

J. M. Dias, G. Toledo, L. Roca +1

By looking at the pseudoscalar-vector meson spectra in the $B ˉ \to J / ψ ρ K ˉ$ and $B ˉ \to J / ψ K ˉ^{*} π$ weak decays, we theoretically investigate the double-pole structu…

$Ξ_{bb}$ and $Ω_{bbb}$ molecular states

J. M. Dias, Qi-Xin Yu, Wei-Hong Liang +3

Using the vector-exchange interaction in the local hidden gauge approach, which in the light quark sector generates the chiral Lagrangian, and has produced realistic results for $Ω…

Molecular $Ξ_{b c}$ states from meson-baryon interaction

Qi-Xin Yu, J. M. Dias, Wei-Hong Liang +1

We have studied the meson-baryon interaction in coupled channels with the same quantum numbers of $Ξ_{b c}$ . The interaction is attractive in some channels and of sufficient intensi…

Doubly charmed $Ξ_{cc}$ molecular states from meson-baryon interaction

J. M. Dias, V. R. Debastiani, J. -Jun Xie +1

Stimulated by the new experimental LHCb findings associated with the $Ω_{c}$ states, some of which we have described in a previous work as being dynamically generated through meson-b…

$Ω_{b}^{-} \to (Ξ_{c}^{+} K^{-}) π^{-}$ and the $Ω_{c}$ states

V. R. Debastiani, J. M. Dias, Wei-Hong Liang +1

We study the weak decay $Ω_{b}^{-} \to (Ξ_{c}^{+} K^{-}) π^{-}$ , in view of the narrow $Ω_{c}$ states recently measured by the LHCb collaboration and later confirmed by the Belle collabora…

Disclosing $D^{} D ˉ^{}$ molecular states in the $B_{c}^{-} \to π^{-} J / ψ ω$ decay

L. R. Dai, J. M. Dias, E. Oset

We study the $B_{c}^{-} \to π^{-} J / ψ ω$ and $B_{c}^{-} \to π^{-} D^{*} D ˉ^{*}$ reactions and show that they are related by the presence of two resonances, the $X (3940)$ and $X (3930)$ , that ar…

Study of the $D K K$ and $D K K ˉ$ systems

V. R. Debastiani, J. M. Dias, E. Oset

Using the Fixed Center Approximation to Faddeev equations we have investigated the $D K K$ and $D K K ˉ$ three-body systems, considering that the $D_{s 0}^{*} (2317)$ acts as the heavy…

Molecular $Ω_{c}$ states generated from coupled meson-baryon channels

V. R. Debastiani, J. M. Dias, W. H. Liang +1

We have investigated $Ω_{c}$ states that are dynamically generated from the meson-baryon interaction. We use an extension of the local hidden gauge to obtain the interaction from the…

Y(3940) as a Mixed Charmonium-Molecule State

R. M. Albuquerque, J. M. Dias, M. Nielsen +1

Using the QCD sum rules approach we study the mass and decay width of the channel $J / ψ + ω$ for the $Y (3940)$ state. We assume that it can be described by a mixed charmonium-molecul…
