Multiplicity dependence of mean transverse momentum in e +e - annihilations at LEP energies

1992
A strong increase of the mean transverse momentum 〈pt〉 with the number of charged particlesnch is observed in e+e- annihilationsinto hadronsat LEP energies. The effect resembles correlations observed in hadron-hadroninteractions. In e+e- annihilationsthe 〈pt〉 and nch correlations can be accounted for by gluonradiation.
