Study of the timelike electromagnetic form factors of the $Λ_{c}$

Di Guo, Qin-He Yang, Ling-Yun Dai

In this paper, the reaction of electron-positron annihilation into $Λ_{c}^{+} Λ ˉ_{c}^{-}$ is investigated. The $Λ_{c}^{+} Λ ˉ_{c}^{-}$ scattering amplitudes are obtained by solving the Lippmann…

New insights into the doubly charmed exotic mesons

Di Guo, Qin-He Yang, Ling-Yun Dai +1

Using effective Lagrangians constrained by the heavy quark spin symmetry and chiral symmetry, for the light quarks, we analyze the $D^{0} D^{0} π^{+}$ , $D ˉ^{0} D^{0} π^{0}$ and $D^0\bar{D}^{…

Study of $X (6900)$ with unitarized coupled channel scattering amplitudes

Shi-Qing Kuang, Qi Zhou, Di Guo +2

In this paper, we study the resonant state $X (6900)$ . The scattering amplitudes of coupled channels, $J / ψ J / ψ$ - $J / ψ ψ (2 S)$ - $J / ψ ψ (3770)$ , are constructed with the interaction of four…

Structure around $p p ˉ$ threshold in $J / ψ$ radiative decays

Qin-He Yang, Di Guo, Ling-Yun Dai

In this paper, we study the structure around the $p p ˉ$ threshold that appears in $η^{'} π^{+} π^{-}$ , $3 (π^{+} π^{-})$ and $K_{S}^{0} K_{S}^{0} η$ invariant mass spectra in the processes of relevant…

Nature of the $X (6900)$ in partial wave decomposition of $J / ψ J / ψ$ scattering

Qi Zhou, Di Guo, Shi-Qing Kuang +2

In this letter, we perform partial wave decomposition on coupled-channel scattering amplitudes, $J / ψ J / ψ$ - $J / ψ ψ (2 S)$ - $J / ψ ψ (3770)$ , to study the resonance appears in these processes.…
