Discontinuity calculus and applications to two-body coupled-channel scattering

Hao-Jie Jing, Xiong-Hui Cao, Feng-Kun Guo

We present a novel method, termed discontinuity calculus, for computing discontinuities of complex functions. This framework enables a systematic investigation of both analytic con…

Novel method for determining the light quark mass ratio using $η^{'} \to η π π$ decays

Adolfo Guevara, Feng-Kun Guo, Hao-Jie Jing

We propose a novel approach for extracting symmetry breaking effects from symmetry conserving three-body decays. The method is based on mapping the Dalitz plot to a unit disk, and…

Covariant orbital-spin scheme for any spin based on irreducible tensor

Hao-Jie Jing, Di Ben, Shu-Ming Wu +2

In hadron spectrum physics, the partial wave analysis is a primary method used to extract properties of hadronic resonances. The covariant orbital-spin coupling scheme holds unique…

Spin-orbit amplitudes for decays with arbitrary spin

Xiao-yu Li, Xiang-Kun Dong, Hao-Jie Jing

In this paper, we propose a method to construct the decay amplitudes in the orbital ( $L$ ) and spin ( $S$ ) coupling scheme for particles with arbitrary spins. For the $1 \to 2$ decay…

Possible precise measurements of the $X (3872)$ mass with the $e^{+} e^{-} \to π^{0} γ X (3872)$ and $p p ˉ \to γ X (3872)$ reactions

Shuntaro Sakai, Hao-Jie Jing, Feng-Kun Guo

It was recently proposed that the $X (3872)$ binding energy, the difference between the $D^{0} D ˉ^{* 0}$ threshold and the $X (3872)$ mass, can be precisely determined by measuring t…

Exploring possible triangle singularities in the $Ξ_{b}^{-} \to K^{-} J / ψ Λ$ decay

Chao-Wei Shen, Hao-Jie Jing, Feng-Kun Guo +1

We analyze possible singularities in the $J / ψ Λ$ invariant mass distribution of the $Ξ_{b}^{-} \to K^{-} J / ψ Λ$ process via triangle loop diagrams. Triangle singularities in the physical…

Graphic Method for Arbitrary $n$ -body Phase Space

Hao-Jie Jing, Chao-Wei Shen, Feng-Kun Guo

In quantum field theory, the phase space integration is an essential part in all theoretical calculations of cross sections and decay widths. It is also needed for computing the im…

Triangle singularities in $J / ψ \to η π^{0} ϕ$ and $π^{0} π^{0} ϕ$

Hao-Jie Jing, Shuntaro Sakai, Feng-Kun Guo +1

The BESIII Collaboration recently reported the observation of the $a_{0} (980)^{0} - f_{0} (980)$ mixing in the isospin breaking decay $J / ψ \to η π^{0} ϕ$ . In the Dalitz plot for that decay with…

Decays of $P_{c}$ into $J / ψ N$ and $η_{c} N$ with heavy quark spin symmetry

Shuntaro Sakai, Hao-Jie Jing, Feng-Kun Guo

We investigate the consequences of heavy quark spin symmetry (HQSS) on hidden-charm pentaquark $P_{c}$ states. As has been proposed before, assuming the $P_{c} (4440)$ and the $P_c(4457…

Isospin breaking decays as a diagnosis of the hadronic molecular structure of the $P_{c} (4457)$

Feng-Kun Guo, Hao-Jie Jing, Ulf-G. Meißner +1

The LHCb Collaboration announced the observation of three narrow structures consistent with hidden-charm pentaquark states. They are candidates of hadronic molecules formed of a pa…

Disentangling the role of the $Y (4260)$ in $e^{+} e^{-} \to D^{} D ˉ^{}$ and $D_{s}^{} D ˉ_{s}^{}$ via line shape studies

Si-Run Xue, Hao-Jie Jing, Feng-Kun Guo +1

Whether the $Y (4260)$ can couple to open charm channels has been a crucial issue for understanding its nature. The available experimental data suggest that the cross section line s…
