Tensor Amplitudes for Partial Wave Analysis of ψ→ΔΔ¯ within Helicity Frame

We have derived the tensor amplitudes for partial wave analysis of ψ→ΔΔ¯, Δ→pπ within the helicity frame, as well as the amplitudes for the other decay sequences with same final states. These formulae are practical for the experiments measuring ψ decaying into pp¯π+π− final states, such as BESIII with its recently collected huge J/ψ and ψ(2S) data samples.
