庞彩莹 %A 平荣刚 %J 中国物理快报 %D 2007 %I %X Based on the naive quark model, we calculate angular distributions for heavy quarkonium decays into pN* (1440), decuplet baryon pairs, and octet-decuplet baryon pairs. The general formulae of angular distributions are given explicitly. Quark mass effects on the violation of the helicity conservation and the prospect to look for them in J/ψ hadronic decays are discussed. %K 02 %K 70 %K Uu %K 13 %K 20 %K Gd %K 14 %K 20 %K Gk
