Abstract: | In e+e? annihilation there are regions of high spherocity S and low thrust in which these distributions are given in QCD perturbation theory by the subprocesses e+e? → qq?GG and e+e? → qq?qq? neglecting only cubic and higher order terms in αS. We give the corresponding QCD predictions which suggest that the calculable corrections to these variables may be slowly convergent. |
