In a recent paper, evidence was presented for a significant, positive corre
lation between the total transverse momenta of particles on opposite hemisp
heres of hadronic events. A new, model independent analysis of the data has
been made. Two components can be distinguished in the correlation, and qua
ntitative estimates of each are given. The results form a significant test
of Monte Carlo models and some of the physics behind them. (C) 1999 Publish
