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…
