Triangle singularity and a possible ϕp resonance in the Λc+→π0ϕp decay

We study the Λc+→π0ϕp decay by considering a triangle singularity mechanism. In this mechanism, the Λ+c decays into the K⁎Σ⁎(1385), the Σ⁎(1385) decays into the π0Σ (or Λ), and then the K⁎Σ (or Λ) interact to produce the ϕp in the final state. This mechanism produces a peak structure around 2020 MeV...
