Description
In this talk, the triangle singularity mechanism is investigated in the two reactions of ψ decay, ψ(2S) → $p \bar{p} \eta$ and ψ(2S) →π +π−K+K−. They would generate a very narrow peak in the invariant mass spectrum of final states. In these processes, all the involved vertices are constrained by the experimental data. Thus, we can make a precise prediction here. We expect these effects can be observed by the Beijing Spectrometer and Super Tau-Charm Facility in the future.
