Theoretical formalism and Monte Carlo study of partial wave analysis for<i>J</i>/Ψ →<i>p</i>ω

Abstract

There are many advantages to using the J/Ψ decay process in studying the structures of hadrons. In order to reveal N* resonances using J/Ψ → pω data at the Beijing Electron Positron Collider, we provide a theoretical formalism and a Monte Carlo study of the partial wave analysis for this channel. We derive the decay amplitudes for various intermediate resonant states in the framework of the relativistic covariant tensor formalism. By performing the Monte Carlo simulation, we obtain the angular distributions, the pω(ω) invariant mass spectra and Dalitz plots for various partial waves in the process of J/Ψ → pω.
