Detecting the pure triangle sigularity effect through the $ψ (2 S) \to p p ˉ η / p p ˉ π^{0}$ process

Qi Huang, Chao-Wei Shen, Jia-Jun Wu

In this work, the triangle singularity mechanism is investigated in the $ψ (2 S) \to p p ˉ η / p p ˉ π^{0}$ process. The triangle loop composed by $J / ψ$ , $η$ and $p$ has a singu…

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…

Decay behaviors of possible $Λ_{c c ˉ}$ states in hadronic molecule pictures

Chao-Wei Shen, Jia-Jun Wu, Bing-Song Zou

In 2010, $Λ_{c c ˉ}^{*}$ states were predicted as the strange number $S = - 1$ partners of $N_{c c ˉ}^{*}$ , which are well known now as the $P_{c}$ states and observed experimentally…

Decay behavior of the strange and beauty partners of $P_{c}$ hadronic molecules

Yong-Hui Lin, Chao-Wei Shen, Bing-Song Zou

We extend our previous study on the decay behavior of $P_{c}$ hadronic molecules to their strange and beauty partners. While $P_{c} (4380)$ and $P_{c} (4450)$ locate just below the $\bar D…
