Abstract
A strong increase of the mean transverse momentum 
pt
with the number of charged particles nch is observed in e+e − annihilations into hadrons at LEP energies. The effect resembles correlations observed in hadron-hadron interactions. In e+e− annihilations the Pt and nch correlations can be accounted for by gluon radiation.
