Precision Sum Rule for Nucleon Isovector Polarizabilities and the Proton-Neutron Mass Difference

Xiong-Hui Cao, Ling-Yun Dai, Feng-Kun Guo

The precision of the electromagnetic proton-neutron mass difference $δ m_{QED}$ extracted from the Cottingham formula hinges on a subtraction function whose low-energy normal…

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…

Two body final states production in electron-positron annihilation and their contributions to $(g - 2)_{μ}$

Shi-Jia Wang, Zhen Fang, Ling-Yun Dai

In this paper, we study the processes of $e^{+} e^{-}$ annihilation into two body final states, either two pseudoscalar mesons or one meson with a photon. The hadronic vacuum polari…

Strong decays of $T_{c s ˉ 0} (2900)^{++ /0}$ as a fully open-flavor tetraquark state

Ding-Kun Lian, Wei Chen, Hua-Xing Chen +2

We have studied the strong decay properties of the recently observed $T_{c s ˉ 0}^{a} (2900)^{++ /0}$ by considering it as a $c u d ˉ s ˉ / c d u ˉ s ˉ$ fully open-flavor tetr…

Tension between $e^{+} e^{-} \to η π^{-} π^{+}$ and $τ^{-} \to η π^{-} π^{0} ν_{τ}$ data and non-standard interactions

Saray Arteaga, Ling-Yun Dai, Adolfo Guevara +1

We show the discrepancy between the isospin-rotated $e^{+} e^{-} \to η π^{-} π^{+}$ cross-section -- measured by various collaborations -- and the Belle $τ^{-} \to η π^{-} π^{0} ν_{τ}$ spectrum, which canno…

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…
