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.…

New insights into the oscillation of the nucleon electromagnetic form factors

Qin-He Yang, Ling-Yun Dai, Di Guo +3

The electromagnetic form factors of the proton and the neutron in the timelike region are investigated. Electron-positron annihilation into antinucleon-nucleon ( $N ˉ N$ ) pairs is…
