Correlation function for the $T_{bb}$ state: Determination of the binding, scattering lengths, effective ranges and molecular probabilities

A. Feijoo, L. R. Dai, L. M. Abreu +1

We perform a study of the $B^{*+} B^{0}, B^{* 0} B^{+}$ correlation functions using an extension of the local hidden gauge approach which provides the interaction from the exchange of ligh…

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…

The isospin and compositeness of the $T_{cc} (3875)$ state

L. R. Dai, L. M. Abreu, A. Feijoo +1

We perform a fit to the LHCb data on the $T_{cc} (3875)$ state in order to determine its nature. We use a general framework that allows to have the $D^{0} D^{*+}$ , $D^{+} D^{* 0}$ compon…

Femtoscopic correlation function for the $T_{cc} (3875)^{+}$ state

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

We have conducted a study of the femtoscopic correlation functions for the $D^{0} D^{*+}$ and $D^{+} D^{* 0}$ channels that build the $T_{cc}$ state. We develop a formalism that allows us…

The $Ξ (1620)$ and $Ξ (1690)$ molecular states from $S = - 2$ meson-baryon interaction up to next-to-leading order

A. Feijoo, V. Valcarce, V. K. Magas

We have studied the meson-baryon interaction in the neutral $S = - 2$ sector using an extended Unitarized Chiral Perturbation Theory, which takes into account not only the leading Wei…

Shedding light on the $X (3930)$ and $X (3960)$ states with the $B^{-} \to K^{-} J / ψ ω$ reaction

L. M. Abreu, M. Albaladejo, A. Feijoo +2

We have studied the contribution of the state $X (3930)$ , coming from the interaction of the $D D$ and $D_{s}^{+} D_{s}^{-}$ channels, to the $B^{-} \to K^{-} J / ψ ω$ decay. The pu…
