Twist-3 contributions to $γ γ \to π^{0} π^{0}, K_{S}^{0} K_{S}^{0}$ in $k_{T}$ factorization

Jun-Kang He, Cong Wang

We compute the cross sections for the two-photon processes $γ γ \to π^{0} π^{0}$ and $γ γ \to K_{S}^{0} K_{S}^{0}$ in $k_{T}$ factorization, including the chirally enhanced two-parton twist-3 light-con…

Combined analysis on nature of $X (3960)$ , $χ_{c 0} (3930)$ , and $X_{0} (4140)$

Zuo-ming Ding, Jun He

In this work, a study of the $D_{s} D ˉ_{s}$ interaction and its couplings to the channels $D D ˉ$ and $J / ψ ϕ$ is performed in a quasipotential Bethe-Salpeter equation approach. T…

Molecular states from $B ˉ^{(*)} N$ interactions

Zhong-Yi Jian, Hong Qiang Zhu, Feng Yang +3

In 2019, two new structures $Λ_{b} (6146)$ and $Λ_{b} (6152)$ were observed by the LHCb Collaboration at the invariant mass spectrum of $Λ_{b}^{0} π^{+} π^{-}$ , which aroused a hot discussion…
