The effective radius for production of baryon-antibaryon pairs from $\psi$ decays

Shu-Ming Wu, Jia-Jun Wu, Bing-Song Zou

By using the covariant L-S Scheme for the partial wave analysis, we deduce the ratios between the S-wave and D-wave contributions from the recent data of $ψ(1^-) \to B_8(1/2^+) \ba…
