Spin polarization and quantum entanglement of baryon-antibaryon pairs produced in electron-positron annihilation

Cheng Chen, Ju-Jun Xie

In this work, we systematically investigate the evolution of spin polarization and quantum entanglement in cascade decays of baryon-antibaryon pairs, which are produced in electron…

Generalizing the Soffer Bound: Positivity Constraints on Parton Distributions of Spin-3/2 Particles

Dongyan Fu, Yubing Dong, S. Kumano +1

We derive the complete set of positivity bounds for the leading-twist parton distribution functions (PDFs) of a spin-3/2 hadron for the first time. This work generalizes the Soffer…

Singly Cabibbo-suppressed hadronic weak decays of the $Ω^{-}$ hyperon

Ye Cao, Tao Zhong, Ju-Jun Xie +1

We study the two-body hadronic weak decays of the $Ω^{-}$ hyperon with strangeness $S = - 3$ , including three singly Cabibbo-suppressed decay modes: $Ξ^{0} π^{-}$ , $Ξ^{-} π^{0}$ and $Λ K^{-}$ . The…

Determination of the binding and $D K$ probability of the $D_{s 0}^{*} (2317)$ from the $(D ˉ K ˉ)^{-}$ mass distributions in $Λ_{b} \to Λ_{c} (D ˉ K ˉ)^{-}$ decays

Hai-Peng Li, Wei-Hong Liang, Chu-Wen Xiao +2

We study the $Λ_{b} \to Λ_{c} D ˉ^{0} K^{-}$ and $Λ_{b} \to Λ_{c} D^{-} K ˉ^{0}$ decays which proceed via a Cabibbo and $N_{c}$ favored process of external emission, and we determin…

The $Σ$ and $Ξ$ electromagnetic form factors in the extended vector meson dominance model

Bing Yan, Cheng Chen, Ju-Jun Xie

We propose a phenomenological extended vector meson dominance model for the baryon electromagnetic structure, and it is found that the current experimental data on the $Σ$ and $Ξ$ …

Hadron spectroscopy at STCF

Feng-Kun Guo, Haiping Peng, Ju-Jun Xie +1

Despite that quantum chromodynamics, the theory of strong interaction, has colorful quarks and gluons as its basic degrees of freedom, all fundamental particles participating the s…

$Ξ_{bb}$ 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…

Triangle singularity enhancing isospin violation in $B ˉ_{s}^{0} \to J / ψ π^{0} f_{0} (980)$

Wei-Hong Liang, S. Sakai, Ju-Jun Xie +1

We perform calculations for the $B ˉ_{s}^{0} \to J / ψ π^{0} f_{0} (980)$ and $B ˉ_{s}^{0} \to J / ψ π^{0} a_{0} (980)$ reactions, showing that the first one is isospin-suppressed while the second o…

Wei-Hong Liang, Ju-Jun Xie, E. Oset

We study the $χ_{c 1} \to η π^{+} π^{-}$ decay, paying attention to the production of $f_{0} (500)$ , $f_{0} (980)$ and $a_{0} (980)$ from the final state interaction of pairs of mesons that can l…

Wei-Hong Liang, R. Molina, Ju-Jun Xie +2

We investigate the decay of $B ˉ^{0} \to K ˉ^{* 0} R$ and $B ˉ_{s}^{0} \to ϕR$ with $R$ being the $X (4160)$ , $Y (3940)$ , $Z (3930)$ resonances. Under the assumption that these stat…

Plausible explanation of the $Δ_{5/ 2^{+}} (2000)$ puzzle

Ju-Jun Xie, A. Martínez Torres, E. Oset +1

From a Faddeev calculation for the $π - (Δ ρ)_{N_{5/ 2^{-}} (1675)}$ system we show the plausible existence of three dynamically generated $I (J^{P}) = 3/2 (5/ 2^{+})$ baryon states below 2…

Faddeev fixed-center approximation to the $N K ˉ K$ system and the signature of a $N^{*} (1920) (1/ 2^{+})$ state

Ju-Jun Xie, A. Martínez Torres, E. Oset

We perform a calculation for the three body $N K ˉ K$ scattering amplitude by using the fixed center approximation to the Faddeev equations, taking the interaction between $N$ …
