Covariant Tensor Analysis Method for J/ψ→ppω

  • In the framework of the relativistic covariant tensor formalism,the effective vertices for decay process J/ψ→pω with various intermediate N* states are studied carefully,and the corresponding amplitudes are derived. By performing Monte Carlo simulation,angular distributions pω(ω) invariant mass spectra and Dalitz plots for various partial waves in the J/ψ→pω process are obtained. It can be found that different partial waves give distinguishable distributions.

Abstract: In the framework of the relativistic covariant tensor formalism,the effective vertices for decay process J/ψ→pω with various intermediate N* states are studied carefully,and the corresponding amplitudes are derived. By performing Monte Carlo simulation,angular distributions pω(ω) invariant mass spectra and Dalitz plots for various partial waves in the J/ψ→pω process are obtained. It can be found that different partial waves give distinguishable distributions.
