THE MOMENT ANALYSIS FOR THE J/ψ HADRONIC DECAY PROCESS

Hen Q

Open publisher page 0 citations

Abstract

In this paper we give the helicity formalism of the angular distribution for process e~++ e~-→J/ψ→V + X, V→P_1P_2 or P_1P_2P_3 and X→PP simultaneously. By using this formalism the moment analysis and some relations have been obtained, which is helpful in determining the spin J_x of the boson resonance X and the helicity amplitude ratios of the process J/ψ→V+X.
