A Moment Analysis for the J/ψ Hadronic Decay Processes

  • In this paper the helicity formalism of the angular distributions for processes e+e-→J/ψ→V + X, V→P1P2 or V→P1P2P3 and X→PP are given simultaneously. On the basis of the formalism a moment analysis is made and some relations are obtained which can be used for determining the spin Jx of the boson resonance X and the helicity amplitude ratios of the process/ψ→V + X.

Abstract: In this paper the helicity formalism of the angular distributions for processes e+e-→J/ψ→V + X, V→P1P2 or V→P1P2P3 and X→PP are given simultaneously. On the basis of the formalism a moment analysis is made and some relations are obtained which can be used for determining the spin Jx of the boson resonance X and the helicity amplitude ratios of the process/ψ→V + X.
