A note on the tensor and vector exchange contributions to $K K ˉ \to K K ˉ, D D ˉ \to D D ˉ$ and $π^{+} π^{-} \to π^{+} π^{-}$ reactions

Luciano M. Abreu, Jing Song, Pedro C. S. Brandão +1

In this note we study the tensor and vector exchange contributions to the elastic reactions involving the pseudoscalars mesons $π^{+} π^{-}$ , $K^{+} K^{-}$ and $D^{+} D^{-}$ . In the case…

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…

$B^{+}$ decay to $K^{+} η η$ with ( $η η$ ) from the $D D ˉ (3720)$ bound state

Pedro C. S. Brandão, Jing Song, Luciano M. Abreu +1

We search for a $B$ decay mode where one can find a peak for a $D D ˉ$ bound state predicted in effective theories and in Lattice QCD calculations, which has also been claimed…

The role of meson interactions in the $D_{s}^{+} \to π^{+} π^{+} π^{-} η$ decay

Jing Song, A. Feijoo, E. Oset

We perform a theoretical study of the $D_{s}^{+} \to π^{+} π^{+} π^{-} η$ decay. We look first at the basic $D_{s}^{+}$ decay at the quark level from external and internal emission. Then h…

Test of the hyperon-nucleon interaction within leading order covariant chiral effective field theory

Jing Song, Zhi-Wei Liu, Kai-Wen Li +1

Motivated by the recent experimental measurements of differential cross sections of the $Σ^{-} p$ elastic scattering in the momentum range of $470$ to $850$ MeV $/ c$ by the J-PARC E$…

$^{3} S_{1} -^{3} D_{1}$ coupled channel $Λ_{c} N$ interactions: chiral effective field theory vs. lattice QCD

Jing Song, Yang Xiao, Zhi-Wei Liu +2

We study the lattice QCD $Λ_{c} N$ phase shifts for the $^{3} S_{1} -^{3} D_{1}$ coupled channel using both the leading order covariant chiral effective theory and the next-to-leading order n…

Strangeness $S = - 3$ and $- 4$ baryon-baryon interactions in relativistic chiral effective field theory

Zhi-Wei Liu, Jing Song, Kai-Wen Li +1

The strangeness $S = - 3$ and $- 4$ baryon-baryon interactions are investigated in the relativistic chiral effective field theory at leading order. First, the potentials are derived fr…

$Λ_{c} N$ interaction in leading order covariant chiral effective field theory

Jing Song, Yang Xiao, Zhi-Wei Liu +3

We study the $Λ_{c} N$ interaction in the covariant chiral effective field theory (ChEFT) at leading order. All the relevant low-energy constants are determined by fitting to the lat…

Strangeness $S = - 1$ hyperon-nucleon interactions: chiral effective field theory vs. lattice QCD

Jing Song, Kai-Wen Li, Li-Sheng Geng

Hyperon-nucleon interactions serve as basic inputs to studies of hypernuclear physics and dense (neutron) stars. Unfortunately, a precise understanding of these important quantitie…
