Helicity Formalism of the Angular Distributions for the Process e++e→J/ψ→V+X,X→3P

  • The helicity formalism of the angular distributions for the process e++e→J/ψ→V+X,X→P1+P2+P3(V and stand for vr and psealar meson, respectvely) are given in this paper. It provides the theical formula for determining the spin and parity of the intermediate state X of the above process.

Abstract: The helicity formalism of the angular distributions for the process e++e→J/ψ→V+X,X→P1+P2+P3(V and stand for vr and psealar meson, respectvely) are given in this paper. It provides the theical formula for determining the spin and parity of the intermediate state X of the above process.
